My approach to leadership is very simple.  It only has 2 parts:

1. I love people, and I try my best to behave in ways that inspire love and admiration from my people.

2. I don’t give a damn whether my people love or admire me.

I think that combining [1] and [2] is very powerful.  Many leaders I observe can only do one or the other, so they are less effective than they could be.

Update 2013/08/10: Evelyn Woods calls it “unconditional leadership”.  I really like it.
