One day I realized that having patience and focusing on gradual improvement rather than quick fixes was necessary for deeply ingrained problems (like forms of akrasia).

Some others:

1. Taking breaks is not negotiable.

2. Maintaining social contact with someone is your responsibility, not theirs.

3. If you try to have too much control in your life, you'll become brittle and unable to handle unexpected changes.

4. "Willpower" is basically worthless. The best productivity strategy is to make productivity habitual.

   4.5. You spend the vast majority of your waking day completely unconscious, doing whatever you're habitually used to doing.

5. Adopting political labels is a negative sum game.
