G. Mark’s Answer
I won't tell you what career to choose, but how to find the career that's good for you and that will give you fulfillment. What you want to do is see how your personality matches others who enjoy and are successful in a wide variety of careers. There are surveys or questionnaires available that will go through a long set of questions, usually multiple-choice. The analysis is of course computerized, and it matches your responses to exactly those people -- those that are happy and successful in those careers.
I say this because I really believe that being happy in a career is a win-win proposition. I tell my students that you are likely to be good at what you enjoy, and you are likely to enjoy what you are good at. And if you enjoy what you do, others around you will benefit as well.
We often talk about money and happiness and how they're related. We also know that there are rather poor people who are happy and rich people who are miserable. But we don't often find someone who is very good at what they do and hate it, or love what they do and are terrible at it.
So that's my advice. Take the easy, straightforward approach. Take a personality assessment test like, for example, RIASEC. I'm sure local colleges or employment agencies can point you to a source. It's more efficient than simply hoping you bump into someone who has your ideal job by chance. Once you get a list of careers you seem to fit into, seek out those people. The test is fun, cheap and very effective. And may surprise you. I for example matched well with exactly what I do, but also Park Ranger. I didn't choose that particular career, mind you, but it did give me something to think about in my personality. Like I said, easy, fun, cheap. What's not to like?
