I love to sing and I do think that my strength as a singer is... I think I have a voice that is certainly sufficient under most any circumstances... but I think my strength is that I really am an actor and I really do have to own what I am saying.
If you want to be a rock star or just be famous then run down the street naked you'll make the news or something. But if you want music to be your livelihood then play play play and play! And eventually you'll get to where you want to be.
