The most human thing about anyone is a thing he learns and … and earns. It’s a thing he can’t have when he’s very young; if he gets it at all, he gets it after a long search and a deep conviction. After that it’s truly part of him as long as he lives.

So it operates badly. So kick the obsession out; start functioning the way you were designed to function.
