...and it can be applied to many aspects of life. I will say this and it echoes what was said earlier. I believe that ANYTHING done without discipline is unwholesome behavior. If you are not doing it ON PURPOSE then it is potentially destructive. But I see nothing wrong with striving for excellence in whatever you do as long as it is kept in perspective and does not detract from having a balanced life. In fact, I would say in the right circumstances finding success in this hobby could promote confidence in those with little that would spread into other areas of one's life.
