It is not naive to think that your job should make your life better. If you are spending 40, 50, 60 hours a week doing something that is not making your life better, then perhaps it's time to rethink what your doing. This doesn't mean that the work isn't hard or challenging, but it does mean that your job should add happiness and fulfillment to your life. It's not about the money, but the actual happiness that it brings you when you are doing it. Simple question; does your job make your life better?
