Someone has said there are 3 paths (or types of practitioner) of judo. It goes something like this, but I might remember the details a bit wrong:
One is a competitor, advances quickly in rank, but might end up giving up judo because competition is so hard on one's body
One is practising judo for recreation and fitness, not necessarily advancing much.
One studies judo and it's techniques and philosophies all his life, not necessarily to win competitions
I think it was not Kano, but maybe one of the later senseis (high dan).
