There is a book titled ';What Color Is Your Parachute.'; It might help you find the answer you want. There are a lot of different careers you could choose. I don't know you are what you enjoy, your educational or work background, your likes or dislikes. Without knowing these things it would be difficult to advise you. There are also tests you can take called ';preferences tests.'; These are tests which you answer based upon your preferences. Your answers will identify some possible career choices that you might enjoy. Most colleges and universities offer these tests at no cost to students. They may offer them for a fee to non-students. I believe you may also find some of these type of tests online.
