Grow fast, built to crash. Grow slow, built to last. - James Clear

Never be so busy comparing what you have that you forget how fortunate you are to have it.

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.

The ultimate form of optimization is elimination.

Nothing is more effective than removing the ineffective.
