If you don't know what sort of job you would be doing after graduating high school, I would say go to university. Not only will it help narrow down what it is you want to do for a career, it also opens up several that you would not have been able to get. Just about any job where only a HS diploma is needed is a wage-slave job. A degree makes things a lot easier to get a living wage.
But, some of the "jobs" I've had so far (some paid, some volunteer):
- web developer (get webpage design and content, then make it so)
- internal helpdesk support (inside the company, not with customers)
- public relations coordinator (basically keeping around 650 people updated on various events)
- front desk at the building I live in (mailroom, maintainence requests, lockouts, etc.)
What I'm attempting to become is a software developer, probably as a consultant. So instead of making shrink-wrapped software, visit a client, see what software automation can be used, see how people would use it, then create a tool to do the job. I think right now that would be the best fit for me since I like to keep moving on to new problems, rather than spend years focused on one thing. Traditional software companies don't have that flexibility.
Anyway, not sure if that helps any... but do at least apply to university. It will help out in the long run (spoken as someone who is first in the family to go beyond high school).
