Think - soccer. Do people train to be good? Or are they after some kinda certificate?
I don't know that that's the best example. People in soccer train to win soccer games. Whatever their long-term deeper personal motivations for going to practice and trying to perfect their skills, they have a very concrete short term goal to test themselves against and push themselves towards -- can their team win that upcoming soccer game.
And that's even at recreational levels where there may not be any real tangible reward in winning the next game -- it's mostly just exciting to succeed at a goal you had.
