" As you go through various stages of your career, you’ll start to realize how much uncertainty there is in the world. It’s a pretty universal truth that once you get the job you thought you wanted, the enjoyment eventually fades and you find yourself looking for something else. You think you want to work for that cool startup, and you get there only to find it’s a mess. You think you want to be a manager, only to discover that the job is hard and not rewarding in the ways you expected. In all of this uncertainty, the only person you can rely on to pull through it is yourself. "
