Let me excuse to attack them one by one.

1. I was very young
Has been a lot of young people in the world of music it was.When they were young, in fact, most people start. Today, young people at the top of maps and music, like Justin Beaver. Michael Jackson began when he was five years old. The fate of the child, and found success when they are teenagers, please see a member there now. Who have not heard of Beyonce? If you're young, you were more successful in the 70s of people might say you have a better shot. We are also # 2, the "old" can not dispel the excuse.
2. I am too old
If not successful in the music industry at age 30, then he remembers he is one of my friends showed me that you quit altogether. Also, the music industry is very strange, making great music rather than that, there could be a focus of a great artist, a friend of me and focus on his time. Al Jarreau was successful when more than 30. At present there is no Boyle, Susan, her features and her age so she has a talent, an international success, has become.
3. I do not have enough money
