Sometimes the brain forgets on purpose

“Work involving higher mental functions, such as analysis and synthesis, needs to be spaced out to allow new neural connections to solidify. New learning drives out old learning when insufficient time intervenes.”

A recent theory on forgetting states that everything we learn remains in storage inside our memory, but our ability to recall and retrieve that information fades if we do not practice fetching information.

We’re no longer weighed down by having to retain trivial data, since all the information we need is one click away, and so we are left with greater cognitive space and with a hard time processing the information we take in to form memories.

• explicit, created through conscious experience;
• implicit, which form when past experiences affect us, sometimes without our knowledge.

Spacing out the repetition, rather than cramming it into one session, is more effective. To use this learning technique:

• Start by establishing a manageable study schedule. 
• Choose a method for storing and organizing information. 
• Don’t forget to test yourself periodically. Tracking your progress will boost your motivation to continue.

In addition to solidifying what we’ve already learned, reflection also helps spark new ideas. And it usually happens when you're not working.

Our most creative ideas don't come when we're consciously focused on the problem. but when we're interacting with people, gaining experiences and letting our minds make connections.

• Get a good night's sleep or take a power nap after learning something new, to help retain and retrieve memories better. Sleep deprivation and acquisition of too much information will not help you save those memories.
• Get moving, to improve the flow of oxygen-rich blood in your brain and to trigger neuron growth and new connections in the brain - critical for memory.
• Improve your diet. Fats from food can build up the brain, resulting to poor blood flow.

Any system or device designed to aid memory:

• patterns of letters or words (common mnemonics)
• ideas (memory palace)
• associations (chunking)

Learning how to learn is critical for everyone. Most of us have to deal with a changing world and to learn how to manage tons of new information.

However, most of our learning methods are outdated and far from optimal. It may even be giving us an illusion of learning, like re-reading and highlighting that don't provide proper feedback to show what you haven't learned.

Focused and diffuse modes provide two models for how we develop, elaborate, deepen and broaden connections. Both methods are important.

• The focused mode of learning is about bringing related concepts together into a unit, called a chunk. 
• The diffuse mode operates through a wider net of connecting general ideas across different fields. We use this diffuse mode while we sleep, exercise or daydream.

Deep engagement with learning makes the experience more valuable and easier to remember.

You can take notes about the material to ask questions later or even send questions by email or ask for an appointment.

Continuing education is vital to maintain your career growth. Lifelong learners view their education as a portfolio with several components.

If you want to earn more, consider learning sales and marketing skills. Those skills are useful even for non-sales jobs.

Most of us can type very fast, but research shows writing your notes by hand will allow you to learn more.

Taking notes by hand enhances both comprehension and retention.

Studying over a period of time is more effective than waiting until the last minute.

Distributed practice works because each time you try to remember something, the memory becomes harder to forget.

When learning is difficult, you're doing your best learning, in the same way that lifting a weight at the limit of your capacity makes you stronger. 

When you keep trying to remember a piece of information, you interrupt the forgetting process and help cement the memory of that information into your brain. 

It's a strategy of mixing up the type of problems you solve when you're testing yourself.

That way, the testing conditions are more similar to real life, where you first have to figure out what kind of problem you have on your hands and then solve it.
