My favorite quote of all-time, maybe, is [from] Mark Twain: 'Put all your eggs in one basket, and watch the basket carefully.' I tend to think that's what great investor do.

Amazon at $3200 is not a bubble stock—not whatsoever. It's basically decent value.

When Bitcoin went from $17,000 to $3,000, 86% of the people that owned it at $17,000 never sold it.

I think so little of it, it doesn't even bother me when it goes up. When Bitcoin used to go up, I'd go crazy that I didn't own it. When Dogecoin goes up, I just start laughing.

Particularly in this business, the people that love it, like me, are so addicted to it and so intellectually stimulated by it. If you're not and you're in it for the money, you have no chance of competing with these people. They're going to outwork. They're going to out-execute you.

Don't confuse a genius with a bull market.
