The one thing you have to avoid is the risk of ruin. Avoiding ruin means stay out of jail. So, don’t do anything illegal. It’s never worth it to wear an orange jumpsuit. Stay out of total catastrophic loss. Avoiding ruin could also mean you stay out of things that could be physically dangerous or hurt your body. You have to watch your health .Stay out of things that could cause you to lose all of your capital, all of your savings. Don’t gamble everything on one go. Instead, take rationally optimistic bets with big upsides. [
