Peter Drucker who said something like if it can't be measured it can't be managed

Hmm... well, there's a flipside to this, maybe management isn't always necessary? It seems like great leaders don't really manage very much at all, other than perhaps their own communication (with themselves, and others).

Maybe I'm off base here but it seems like we have the potential to accomplish amazing things, simply by managing our state of being, and not doing anything other than what comes naturally.

As an example in my own life, I've noticed that no amount of strategising leads to me getting what I want from my wife. To get what I want, I have to stop being right, laugh at myself, and do what comes naturally, without worrying too much how I'll look.
