Mental toughness immediately increases when you find the right subject. You're more likely to stick with things when you're genuinely interested. - James Clear

Some things are better off ignored than attacked.

Attention is the oxygen of conflict. When you fight a problem, you breathe life into it. When you starve a problem of your attention, you suffocate it.

In a surprising number of cases, the way to solve a problem is to ignore it.

Money is not the only way to improve life. Instead of widening your margin of profit, widen your margin of leisure. Instead of optimizing for money, optimize for time. Instead of seeking efficiency, seek recovery.

To understand others, watch what they reward.

To understand yourself, watch what you envy.
