The idea is that the correct choice is the one that you will feel good about choosing, not matter how it turns out. Plenty of people who feel good about having done a startup, even though it turned out badly. But, plenty of other people who only did it because they thought it would make them rich and successful, and for any startup there is always a good chance of that not being the case. Most startups "fail", in the sense of they don't make anyone rich and eventually get shut down. So, only choose the startup if it's what you want to do, regardless of whether or not it will succeed.
