I started boxing when I was eight. I enjoyed when I could hit someone and they couldn't hit me back. It was like a game for me. The feeling of knocking someone out. My first knockout victory was when I was ten. He went down and his nose started to bleed, so they stopped it.
I believe that we have been doing this not primarily to achieve riches or even honour, but rather because we were interested in the work, enjoyed doing it and felt very strongly that it was worthwhile.
