I bought a company in the mid-'90s called Dexter Shoe and paid $400 million for it. And it went to zero. And I gave about $400 million worth of Berkshire stock, which is probably now worth $400 billion. But I've made lots of dumb decisions. That's part of the game.
Banking is very good business if you don't do anything dumb.
Paradoxically, when 'dumb' money acknowledges its limitations, it ceases to be dumb.
Outstanding long-term results are produced primarily by avoiding dumb decisions, rather than by making brilliant ones.
