That’s the first half of the lecture: the idea that true leadership means being able to think for yourself and act on your convictions.

It seems to me that solitude is the very essence of leadership. The position of the leader is ultimately an intensely solitary, even intensely lonely one. However many people you may consult, you are the one who has to make the hard decisions. And at such moments, all you really have is yourself.

So solitude can mean introspection, it can mean the concentration of focused work, and it can mean sustained reading. All of these help you to know yourself better.
