Limited attention

To avoid thinking about problems all day long, schedule a specific time where you give yourself the freedom to think about the issue you need to make a decision about. 

If thoughts about the issue creep into your brain before your scheduled thinking time, tell yourself “No, I’m going to think about that after dinner, not during this meeting”.

Dwelling on a problem, thinking “this is horrible, I can’t handle this” or rehashing things that happened in the past are an unproductive use of your time.

Thinking about what steps you can take to improve the situation or actively thinking of a solution to the problem are helpful toward moving forward. 

Before jumping to a conclusion, think about the long-term consequences of your decision.

We may respect those able to fling themselves into a hard problem and make a quick choice with seemingly little thought, but making a meaningful decision needs to be done with care for the long-term effects.

It’s important to be aware of what state of mind you’re in before tackling a hard choice.

Decision fatigue happens when the mental energy required to weigh the tradeoffs of our decision becomes too much for us to handle. 

There's only so much that you can achieve working on your own, that's why it's important to delegate effectively. To successfully delegate:

• Explain what your team's role and goals are. Or even formalize it in a team charter, which can also be useful for keeping the team on track.
• Think about the skills, experience and competencies within your team, and start matching people to tasks. 

Whatever approach you prefer to adopt, you also need to bear in mind that different people have different needs when it comes to motivation. 

One size does not fit all. Some individuals are highly self-motivated, while others will under-perform without managerial input, and you need to be able to handle both. 

Urgent but unimportant tasks = distractions.

Urgent tasks put us into constant “reply mode.” Important work is related to planned tasks that move us closer to our goals.

Anytime you are pulled away from your tasks, it takes time to readjust to them when you jump back in (sometimes it can take up to 25 minutes).

Interruptions (notifications, loud noises, social media, checking email etc.) harm your concentration.

"The ability to perform deep work is becoming increasingly rare at exactly the same time it is becoming increasingly valuable in our economy. As a consequence, the few who cultivate this skill, and then make it the core of their working life, will thrive. "

If we are learning for work, then in our brains learning equals work. So we think we have to do it during the day, at our workplace.

We think that walking is not learning. It’s ‘taking a break’. We instinctively believe that reading is learning. Having discussions about what you’ve read, however, is often not considered work, again it’s ‘taking a break’.

When mastering a subject, our brain has two general modes of thinking: focused and diffuse, both important in the learning process.

The focused mode is what we traditionally associate with learning. But we need time to process what we pick up, to get this new information integrated into our existing knowledge. We need time to make new connections. This is where the diffuse mode comes in.

The non-cognitively demanding, logistical-style tasks, often performed while distracted, tend not to create much new value in the world and are easy to replicate.

...is the first element of deep work.

That means you won’t have the mental discipline to stay concentrated on a single task unless you prepare your mind and environment to it.

To improve your mental ability, you have to understand its natural peaks and drops throughout the day. It can be different for every person, so pay attention to what time of the day your mind is functioning at its best.

If you find it difficult to see what time of day your mind is functioning best, keep a productivity log. At two-hour intervals, write down your physical and mental status. You'll find a pattern of peak performance or sluggishness.

Most people have little pockets of time throughout the day, between meetings and calls and emails, with 15 minutes here, and 30 minutes there. To perform at your best depends on simple time management hacks.

• Set aside one or two times a day to check and respond to all your messages and emails, then close your inbox.
• Try and structure your day in one-to two-hour chunks of focused work.
• Introduce a clear protocol for colleagues to contact one another in case of an actual emergency.

You may decide to hold off voicing your opinion if you want to gather your army first. People can contribute experience or information to your thinking — all the things that would make the disagreement stronger or more valid. 

Also, delay the conversation if you’re in a meeting or other public space. Discussing the issue in private will make the powerful person feel less threatened.

Before you share your thoughts, think about what the powerful person cares about. You’re more likely to be heard if you can connect your disagreement to a “higher purpose.” 

State it overtly then, contextualizing your statements so that you’re seen not as a disagreeable underling but as a colleague who’s trying to advance a shared goal. 

The best one for you depends entirely on your working style and personal preferences.

You can use a physical notebook around everywhere you go, but it's easier to use a to-do list app or tool that syncs across all your devices. That way, you can access your to-do items whenever and wherever you need to, whether you're at your desk, in a meeting, or on a business trip.

Write out your to-do list the day before:

• You'll free your time to dive right into your to-do list in the morning - one of the most productive times of day.
• It can help you spot obstacles ahead of time and prepare accordingly.
• Knowing what you have going on well in advance could help you relax and sleep better the night before.
