That's just not the case. It takes a lot to be successful. This is for all three band members. My son was a great drummer at age five and I bought him a drumset and it lasted six months. Then he was into motorcycles after that.
Music is a great profession.
It has its highs and lows. It's nice to do something you love and earn your living at. Playing music is great, but the music business is as difficult as any other business. Don't let any fools, record labels, who don't know any better interfere with your art. I've got three kids and they all love music in the way children love music.
