Charlie Munger

It's good to learn from your mistakes. It's better to learn from other people's mistakes.

It's so simple: you spend less than you earn. Invest shrewdly. Avoid toxic people and toxic activities. Try to keep learning all your life. And do a lot of deferred gratification. If you do all those things, you are almost certain to succeed. And if you don't, you'll need a lot of luck. And you don't want to need a lot of luck. You want to go into a game where you're very likely to win without having any unusual luck.

It is remarkable how much long-term advantage people like us have gotten by trying to be consistently not stupid, instead of trying to be very intelligent.

Whenever you think that some situation or some person is ruining your life, it is actually you who are ruining your life… Feeling like a victim is a perfectly disastrous way to go through life. If you just take the attitude that however bad it is in any way, it’s always your fault and you just fix it as best you can—the so-called iron prescription.
