isn't it about self attainment, relaxation pushing the boundaries, in reality it is no different from any other hobby, (unless it involves living off grid or getting away from society permanently)and like any hobby or pastime you can go into it deeply or just use it to relax, some people like to go walking, fishing, take photographs or even pop down to the allotment for a few hours, enjoyment is the key word, if you enjoy what you are doing, even if you don't do it well, then that is reason for doing it.
