Feynman is proof that depth and joy aren't opposites. One of the greatest physicists who ever lived, and also a guy who played bongos, picked locks, and pulled pranks.
He had zero tolerance for fake understanding. His test was simple: if you can't explain it plainly, you don't actually get it. No hiding behind jargon.
But the thing to steal from him is his relationship with not-knowing. Most of us find uncertainty terrifying. Feynman found it thrilling. He'd rather sit with an honest 'I don't know' than a comfortable wrong answer.
He said the whole reason he did science was 'the pleasure of finding things out.' Not to be right. Not to win. The joy of curiosity itself. If you're lost, that's a way to live — stop needing the answer, start enjoying the looking.
