You answer your question in the last paragraph. Yes that is life. You work hard to achieve your goals(sometimes even others goals that you have mistaken as your own) and once you get there you realize that it was not Nirvana. Having the job/car/house/lifestyle/etc. you dreamed of your entire life still comes with a lot of issues. We tend to think of our life in terms of; when only I get X then my life will be complete. Guess what. It won't. You will still be the same person - only with X. That job/car/spouse/house you put on a pedestal comes with a lot of issues as well. It is absolutely okay to realize that the dream job perhaps wasn't so. Perhaps somewhere else is a better fit. You should not be afraid to change. It is only if you keep changing jobs to find out that everything there is not as expected - then perhaps you should look in the mirror for the common denominator.
