People often think entrepreneurship is a one-idea, one-shot game: you have a great idea and you pursue it until it makes you rich or makes you run back home. That's a shame because it keeps people from exploring entrepreneurship as a career. It's like thinking the only career in music is to be frontman in a rock band. In truth, most entrepreneurs take part in multiple startups before launching their own, and they play many different roles besides the star.
