I had two things I could do: I could run over you, and I could put a good stiff arm on you. That was about it.
If you can react the same way to winning and losing, that's a big accomplishment. That quality is important because it stays with you the rest of your life, and there's going to be a life after tennis that's a lot longer than your tennis life.
Golf without bunkers and hazards would be tame and monotonous. So would life.
