Just for starters only, I suggest that you try the personality test I have copied below. You can find it easily on Google. You can also read about the Briggs Myers (sometimes called the Myers Briggs) test on eNotes by clicking on the reference link below. The Humanetric test is just a sample. It consists of 72 questions about yourself and is intended to indicate what kind of personality you have and therefore what kinds of careers would be most compatible.
If you are in the eleventh grade, it is understandable that you are starting to worry about a career. This is about the time when the high schools ask students to declare a major. You have to start thinking about who you are, what you like, what you don't like, and where you think you want to go in life. However, you still have plenty of time to make final decisions, especially if you plan to go to college.
Most colleges and universities have career counseling services, and I should think there would be some such counseling even at your high school. It is well worth your while to give your career decisions, and even your decision about a major, a lot of thought; because it gets harder and harder to change as you advance in school and later as you advance in life.
Personality test based on C. Jung and I. Briggs Myers type theory provides your type formula, type description, career choices.
I believe there are lots of self-administered tests available on the Internet. You can sample some by Googling things like "self-testing." Psychology Today has a lot of personality tests accessible on the Internet. The tests are free, and part of the results are free--but if you want the complete results of a test you have to pay a small fee.
You are the one who has to find out who you are and where you belong. Don't make a choice to please anybody else. Maybe it takes years to truly understand yourself. You are wise to be concerned about this all-important problem at an early age. LOL.
