I've always just adored music. It's my first love, really. I admire and respect people in the music business. You really have to work hard and diligently. Sometimes actors can be lazy and get away with it, but you can't do that if you're a musician.

Property is the fruit of laborproperty is desirableis a positive good in the world. That some should be rich, shows that others may become rich, and hence is just encouragement to industry and enterprize.

— Abraham Lincoln
