One of my clients used to say about the work "If it was fun, we would charge admission." If someone has to pay you to do it, it's probably not simple fun and games.
Also, if you're meant to be physician (like probably most people here), there is no better job. However, there are plenty of jobs that are easier to do and more enjoyable for most people. Here is what Money Magazine thinks. I'm sure you can find other surveys like this. It comes down to many factors, such as talents, needs, preferences, etc.
