People follow incentives, not advice. - James Clear

The ultimate form of optimization is elimination.

Nothing is more effective than removing the ineffective.

3 things that help habits stick:

1) Repetition. Habits form based on frequency, not time.
2) Stable context. If the context is always changing, so is the behavior. You need a reliable environment.
3) Positive emotions. If it feels good, you'll want to repeat it.

When you tolerate an error, you rob yourself of learning.

When you ruminate on an error, you rob yourself of happiness.

Notice it, improve it, and move on from it.
