• The most scare thing in the world is time because you can earn money but you can not earn more time.• What money does is that it gives you ability to do what you want, when you want, with who you want and for as long as you want.

Money gives you control over your time.

• Studying a specific person can be dangerous because we tend to study extreme examples like billionaires and CEOs.• You’ll get closer to actionable takeaways by looking for broad patterns of success and failure.

Focus less on specific individuals and more on broad patterns.

• The ceiling for social comparison is so high that no one will ever hit it. So it is better to accept that you might have enough.• You reputation, family, friends and happiness are most important things. Stop taking risks that might harm them.

Stick to what you need or have.

• A gap between what could happen in the future and what you need to happen in the future in order to do well is what gives you endurance and endurance is what makes compounding magic over time.• That gap is your room for error.

Worship room for error.

• Highest returns tend to be one-off hits that can’t be repeated.• It’s about earning pretty good returns that you can stick with and which can be repeated for the longest period of time.

Good investing isn’t just about earning the highest return

• Getting money requires taking risks and being optimistic• But keeping money requires the opposite of taking risk. It requires humility and fear that what you’ve made can be taken away from you just as fast.

Getting money and keeping money are two different skills.

• We tend to judge wealth by what we see (Cars, Homes and Instagram photos) but we can’t see people’s bank accounts or brokerage statements.• Wealth is hidden. It’s income not spent.• It is an option not yet taken to buy something later.

Wealth is What You Don’t See.

• Spending beyond a pretty low level of materialism is to show people that you have/had money.• For most people it’s a daily struggle against instincts to show more than they have and keep up with others doing the same.

Most Spendings beyond you need is for show off.

• Everything has a price, and the key to a lot of things with money is to figure out what that price is and pay it.• For investing the price is volatility,fear,doubt and regret.Trying to avoid this price is similar to shoplifting which rarely ends well.

Nothing’s Free.

• Do not aim to be coldly rational when making financial decisions.Aim to just be pretty reasonable.• Reasonable is more realistic and you have a better chance of sticking with it for the long run.

Being reasonable is better than being rational.

• You don’t need a specific reason to save.• It’s great to save for a car or a down payment or a medical emergency. But saving for things that are impossible to predict or define is one of the best reasons to save.

Save. Just save.

Few things to keep in mind if you want to take your personal finance journey seriously.

Doing well with money isn’t necessarily about what you know. It’s about how you behave. And behavior is hard to teach, even to really smart people. Money—investing, personal finance, and business decisions—is typically taught as a math-based field, where data and formulas tell us exactly what to do. But in the real world people don’t make financial decisions on a spreadsheet. They make them at the dinner table, or in a meeting room, where personal history, your own unique view of the world, ego, pride, marketing, and odd incentives are scrambled together. In The Psychology of Money, award-winning author Morgan Housel shares 19 short stories exploring the strange ways people think about money and teaches you how to make better sense of one of life’s most important topics.

The Psychology of Money

Time is a measure of non-stop, consistent change in our surroundings, usually from a specific viewpoint.While the concept of time is self-evident and intuitive – the steady passing of events before our eyes; the orbit of the Moon around our planet – describing its fundamental nature is much harder.Even physicists aren't sure what actually happens when time passes. Although they do have a few hypotheses.

What's Time? (In Science)

For centuries, time was regarded as a constant, independent force, as if the Universe's progress is governed by a single clock.This description of time changed in 1905 with Albert Einstein's theory of special relativity.While the passing of time was already known to be closely connected to space, this monumental theory was the first to combine space and time into a single field, one with measurements that vary depending on the relative motion or gravitational forces of objects within it.Basically, that means time is relative

How does time work?

Two people moving at the same velocity will each agree their measures of distance and time match. As one person changes speed, however, they will see the other's measure of time and distance change, even as their own stays the same.Without any reason to prioritize one perspective of time over another, this means time isn't a constant universal unit at all. It is a relative measurement that varies as objects move faster or slower, or as they're subjected to more or less gravity.Gravity curves space and time: The stronger the gravity, the more it curves space-time, and the more time slows down.

Is time real?

Of course, for us to actually see these effects on time, the change in speed or gravitational pull must be enormous. But as an observer accelerates towards the speed of light, unique measures of time become increasingly noticeable.In theory, as a particle approaches the speed of light, we would see its 'clock' slow down. Once it exceeds the speed of light, its clock would, theoretically, seem in reverse from our point of view. From the particle's point of view, our clock would seem to reverse

Is it possible to reverse time?

similarly, the space-contorting volume beyond the horizon of a black hole also distorts perspectives of time.in our universe, we have freedom of space and can move around as we like, but we're forced to march along time's arrow in a linear direction.Calculations show that crossing over a black hole's horizon would swap those freedoms. So we'd no longer have to follow time's strict arrow of direction, but we'd lose the freedom to move around in space, allowing for time travel (of sorts).

What about time travel?

Models of space-time can describe measurements of time and space varying from one point to the next, but they don't explain much about time's stubborn adherence to a sequence of events.Under these descriptions of time, our Universe is a single block of space-time. There's sort of a beginning – the Big Bang – before which our best understanding of the laws of physics can't be applied. There's sort of an end, where change is no longer measured with any significance. But no single slice of time stands out physically as 'now'.

Why is there a future and a past?

Lively illustrations and fun, accessible text provide an account of the history of time and the evolution of keeping time, from following the sun and the moon to the huge clocks we use today.

About Time

The second as we know it was one introduced in the late 1500s when the Gregorian calendar began to spread across the globe alongside British colonialism. The Gregorian calendar defined a day as a single revolution of the Earth about its axis. A day could be divided into 24 hours, each hour into 60 minutes, and each minute into 60 seconds. Yet, the second was more a mathematical idea than a useful unit of time.

The history of the second

The second only became important when society became interconnected through fast-moving railways where cities needed to agree on exact timekeeping. By the 1950s, several global systems required every second to be accounted for with as much precision as possible.  Today, devices are synchronised to help us maintain a globally consistent time, from radio signal transmitters to satellites for global positioning systems.

The growing importance of the second

As early as 1955, researchers started to develop atomic clocks, which relied on the laws of physics to establish a new foundation for timekeeping. An atom consists of negatively charged electrons orbiting a positively charged nucleus at a consistent frequency. You can lightly disturb an electron's orientation if you expose an atom to an electromagnetic field such as light or radio waves. If you briefly tweak an electron at the right frequency, the vibration will resemble a ticking pendulum and can tick for centuries.

Atomic clocks

Before timekeeping could go fully atomic, countries had to decide which atom would work best.  At the Thirteenth General Conference of the International Committee for Weights and Measures in 1967, researchers decided on Cesium-133. The element conformed to the following specifications:<ul><li>It had a long-lived and high-frequency electron oscillation for precise, long-term timekeeping.</li><li>It maintained a reliably measurable quantum spin </li><li>It could easily vaporise.</li></ul>

Finding the right element

Determining how many ticks of a caesium atom were in a second, the conference used the most precise astronomical measurement of a second available at the time.  They started with the number of days in a year and divided it down. Compared to the atom’s ticking rate, one second was defined as exactly 9,192,631,770 ticks of a caesium-133 atom.

The cesium standard

Discover how scientists developed atomic clocks, which use the vibrations of atoms to measure and maintain a globally consistent time. -- In 1967, researchers gathered to answer a long-running scientific question: just how long is a second? It might seem obvious at first. A second is the tick of a clock, the swing of a pendulum, the time it takes to count to one. But how precise are those measurements? And what is that length based on? John Kitching digs into how we scientifically define this fundamental unit of time. Lesson by John Kitching, directed by Tjoff Koong.

Who decides how long a second is? - John Kitching

To answer a question, more questions must be asked.

Well, the simple answer is most of us feel stuck in the past and can’t get over it and keep dwelling upon it which worsens the condition as if the Past happens to us and we can’t do anything but think more of it.

Why should we even bother about the Past?

Past is not some random place but the memory of some events.If you get a bit deeper into the concepts like Quantum Physics, Time Traveling, and even spirituality you’ll get to know that time and space have a memory. It’s been said that every human has a certain level of energy with a different form of aura, so if I sit on a chair and get away after some time that chair will store a buffer of memory that temporarily filled with my energy prints until unless some other energy source doesn’t alter my energy in that particular memory.

What Is Past?

Past is not about the event itself which causes the suffering but the Effect and the Meaning we derive from that event.

It’s not what happens to us but how we respond to the situation that matters.

Every time you go back to your past you change it. The past is just the raw material to work with. It’s entirely malleable and flexible. You get to take the pieces and choose which ones to discard and how you are going to frame them.

You Can Change Your Past!

As the neuroscientist, Dr. Donna Bridge said, “A memory is not simply an image produced by time-traveling back to the original event — it can be an image that is somewhat distorted because of the prior times you remembered it… Your memory of an event can grow the less precise event to the point of being totally false with each retrieval.”

Yes! You Can Change Your Past!

In physics, there’s a concept known as the observer effect, which shows that the mere observation of a phenomenon inevitably changes the phenomenon.So every time you look at your past it will change because it is just a memory.

Change Your Memory!

“Regardless of what happened to you in the past, no matter how unique, terrible (or wonderful) it was, you have the same ability to shape who you were and who you will become.”Quite literally, you are the Designer of your Past. So create your story which upgrades your present based on your future identity not on the past.

This is the best method I used for getting out of traumatic memory.

Past Is Nothing But A Fiction

In 2009 the British physicist Stephen Hawking held a party for time travellers – the twist was he sent out the invites a year later (No guests showed up). Time travel is probably impossible. Even if it were possible, Hawking and others have argued that you could never travel back before the moment your time machine was built.But travel to the future? That’s a different story.Of course, we are all time travellers as we are swept along in the current of time, from past to future, at a rate of one hour per hour.But, as with a river, the current flows at different speeds in different places.

Time travel: five ways that we could do it  

This is the easiest and most practical way to time travel into the far future – go really fast.According to Einstein’s theory of special relativity, when you travel at speeds approaching the speed of light, time slows down for you relative to the outside world.This is not a just a conjecture or thought experiment – it’s been measured. Using twin atomic clocks (one flown in a jet aircraft, the other stationary on Earth) physicists have shown that a flying clock ticks slower, because of its speed.

1. Time travel via speed

The next method of time travel is also inspired by Einstein. According to his theory of general relativity, the stronger the gravity you feel, the slower time moves.As you get closer to the centre of the Earth, for example, the strength of gravity increases. Time runs slower for your feet than your head. In 2010, physicists at the US National Institute of Standards and Technology (NIST) placed two atomic clocks on shelves, one 33 centimetres above the other, and measured the difference in their rate of ticking. The lower one ticked slower because it feels a slightly stronger gravity.

2. Time travel via gravity

Another way to time travel to the future may be to slow your perception of time by slowing down, or stopping, your bodily processes and then restarting them later.Bacterial spores can live for millions of years in a state of suspended animation, until the right conditions of temperature, moisture, food kick start their metabolisms again. Some mammals, such as bears and squirrels, can slow down their metabolism during hibernation, dramatically reducing their cells’ requirement for food and oxygen.

3. Time travel via suspended animation

General relativity also allows for the possibility for shortcuts through spacetime, known as wormholes, which might be able to bridge distances of a billion light years or more, or different points in time. Many physicists, including Stephen Hawking, believe wormholes are constantly popping in and out of existence at the quantum scale, far smaller than atoms. The trick would be to capture one, and inflate it to human scales – a feat that would require a huge amount of energy, but which might just be possible, in theory.

4. Time travel via wormholes

Another time travel idea, put forward by the American physicist Ron Mallet, is to use a rotating cylinder of light to twist spacetime. Anything dropped inside the swirling cylinder could theoretically be dragged around in space and in time, in a similar way to how a bubble runs around on top your coffee after you swirl it with a spoon. According to Mallet, the right geometry could lead to time travel into either the past and the future.

5. Time travel using light  

In 2009 the British physicist Stephen Hawking held a party for time travellers – the twist was he sent out the invites a year later (No guests showed up).
