i don't want to say that i didn't learn anything from him, because i did.
see, he was a very stupid man. and, very stupid men make large numbers of mistakes over the course of their lives.
he worked hard his whole life and gained nothing from it - there is a valuable lesson to be learned, there. namely, don't waste your life working.
he did much of it for his children, who didn't want what he gave them. another valuable lesson: don't have kids.
he married thrice, and was miserable in all three of the relationships. lesson: don't get married.
kids don't learn in a vacuum. in the long run, i was actually probably better off.
