“Number-one hit songwriter” isn't an entry-level position. Fortunately, it's not your only hope; Barry Manilow wrote jingles for big clients like McDonald's, Chris Isaak composed the theme for the Craig Kilborn Show, Sir Elton John scored big on The Lion King soundtrack, and Quincy Jones is a successful publisher. In a business where competition is the only constant, the more options you have, the better.
