Underappreciated advice: Get friends who are significantly older than you. There's no mimetic competition. Just decades of wisdom they love to share.… - George Mack

Golden rule: Never underestimate someone’s ability to get in their own way.

If you put the 110 billion humans ever to live in one giant room -- alive or age at death -- 40% would be under the age of 5. And 50% would be under the age of 15. Forget waiting for an age like 30 or 40 to do things. You're already elderly.

Never argue with a professional cynic online. Instead, try and find their earliest ever work. Often when I go scroll back far enough, I'll discover an old version of them that had hope, that had optimism, that had agency. And then some rejection happened.
