As you think about your career, whatever you do, don't worry about mapping it all out. Just don't play it safe. Don't be the person who quits a start-up company, or a band, before giving it a chance to make it big. And don't be afraid to start over or change direction. The more risks you take, the happier you will be, even if they don't work out. And I can assure you, sometimes they won't. But I can also assure you this: No matter what job you have, no matter who your employer is, the harder you work, the luckier you will get…. My advice is relatively simple: Continue learning. Continue asking difficult questions. Continue thinking independently. Continue volunteering your time to help others. Continuing defending, and enjoying, the freedoms that make America great.
