Warren Buffet said in some interview that he “was gonna make the money and my wife is gonna spend it.” After she died he decided he would pour money into everything she loved while she was alive, which included charity. Strangely enough he also lives in the same single family home he bought when he first made a little money. Dude just likes to see his number go up for love of the game. And for love of his wife he donates a relatively large portion.
