My son was the same way. Some people are group players and others are not. Some people are natural with sports and some are natural with the arts. My son's father wanted him to play all the sports he played when he was in school which was soccer, hockey, football and so on. But, our son just didn't like those kinds of things. He started playing the guitar when he was 8 and he is 40 today and he has his own recording company and his own band. He has made a great living doing what he loves best. Finally after all these years his Dad has finally gotten it through his head that his son is not into sports but is a great musician. So hang in there and do what you love most. I hope it doesn't take your Dad 40 years to get the point. Good luck to you.
