WHAT KIND OF JOB OR CAREER FiELD SHOULD I BE LOOKING INTO??

Hi im a guy by the way using my gf's answers anyways I am 20, I am trying to find my niche in the world of careers. I am getting to the point to where im getting depressed over not knowing what to do. I'll tell you about me then maybe you can help me with what I should be looking into. I graduated high school in 2006, I am good with computers. I can type fast and took several computer courses in high school including desktop publishing, website design, typing, and advanced computer applications. I dont know if I should look for something in the computer field or something else??? I dont plan on going to college or anything unless I one day get a job and I stay there a while and they say I can get promoted if I go to school for something, then I would but if I went now I wouldnt know what to do, so I think its best right now to just try and find a job. I dont know what to get into though. I know I can work my way up if I get my foot in the door but i dont know where to stick my foot???
