Hey, if you dislike working so much, move to Ireland. American workers actually LIKE working, that's why we're happier. They did an study and found that most europeans were depressed and unhappy, while Americans were upbeat and optimistic. It's not the vacation days you get, it what you do and what your attitude is about what you do.
If you feel non-productive, look into a new career, go back to school and try something different.
