Ultralearning Ch. 5 - Principle 2 - Focus

This chapter covers everything focus-related, from how long focus sessions should be, to flow state, to distractions, to procrastination, to the pomodoro technique, to the right environment, to the right kind of focus.

The gist of this chapter is to minimize distractions and maximize focus, but also take breaks.

I personally do 60-90 minutes of focus time, followed by a 10-20 minute break. This is not a hard rule. Focus time could be less or more depending on how much time I have for that session, and the breaks could be less or more depending on if I eat a small snack or bigger meal, or I have to do some other task such as a chore or errand.
