You don't have to travel, but I find extended travel to be a helpful tool for reexamining yourself and the constraints you've artificially placed on your life. It's easy to believe everything has to be done one way if you're always in one place around the same people.
Tim FerrissExcitement is the more practical synonym for happiness, and it is precisely what you should strive to chase. It is the cure-all.

The question you should be asking isn't, "What do I want?" or "What are my goals?" but "What would excite me?"
