I know that there are people who LOVE music, who will pick up an instrument any chance they get and play it because they love it. My step-son professes to love playing the cello but NEVER picks it up on his own. He only practices when forced to. I don’t think he loves it at all, I think he’s trying to make his mother happy and she tells him that he will be a professional someday. Why practice something you don’t really enjoy? Granted, there may be things we must do for a job, or school that we don’t like and I feel like the above article is for those situations. But for those of us who enjoy our pursuits we can easily spend 10,000 PLUS hours doing it.
