When it comes to success it seems that successful people know what they want and don't give up until they reach their goals. Even the interviews I post here have that in common: every one made a conscientious decision to make their career in the music industry and none of them have ever given up.
If you commit yourself wholeheartedly and believe that what you are doing is the right thing, chances are it is! If you know what you want, you have a goal and are committed to obtaining it then sooner or later it happens!
