On the other hand, I think many other people I've talked to who have only worked for a few years kind of feel lost. I guess in a way we've been so busy with school and constantly pressured into finding a good paying job and that it would all be worth it that we didn't take enough time to experience life and find out what actually makes us happy. In fairness, it's also a bit difficult to know if you'll enjoy a job until you actually do it for a while.
I like my job, don't get me wrong, and I really do appreciate all the opportunities it gives me. I think the real question is whether that job enables you to do what you truly want to do, or handicaps you instead. I am fortunate enough that my job is the former, but I've certainly taken jobs where it was more the latter.
