Happiness/Work
Unless you are planning to raise a child, it is likely that you will spend 40 hours a week doing some sort of paid work. As a result, choosing a profession can be as important of a decision as choosing a spouse.
When college students decide on a major, a common question is, "Should I choose the major that will make more money, or choose the one I enjoy most?"
There is no simple answer to this question. Some students have financial constraints, and need to pay off debts and support their families. For them, a good paying job is essential. Other people enjoy making money, so their answer to the question would be, "both."
