I do not know anyone who has got to the top without hard work. That is the recipe. It will not always get you to the top, but should get you pretty near.
The point, which can hardly be repeated too often, is that differentiation is not separation. The head and the feet are different, but not separate, and though man is not connected to the universe by exactly the same physical relation as branch to tree or feet to head, he is nonetheless connected - and by physical relations of fascinating complexity.
I love boxing and it did a lot for me. But sometimes it made me think how savage human beings could be to each other. That wasn't the kind of boxer I wanted to be. My strategy was to be as scientific as I could when I fought. I didn't want to be seriously hurt, and I didn't want to do that to anybody else either.
