This is a question that I hear all the time. And you know what? Very few high school students really know what they want to do when they grow up.
When I was growing up computers were something we had heard about but had never seen. My first experience with a computer was in high school. We had a teletype machine (look it up) and created strips of paper with holes punches in them using BASIC language. We would send that strip of paper over a phone line to a computer 200 miles away and it would create our program and send it back to us several days later.

There were virtually no jobs in the computer industry back then. Now, there are millions.
In the world economy we now live in, new fields are being create on an almost daily basis. Millions of jobs will exist 20 years from now that we can not even imagine at this time.
How do you prepare for that world of employment? Learn to think. Learn to communicate. Learn to learn.
So, what college do you go to? Find one that fits you. Find one that is going to teach you to think, to communicate and be a life long learning. If you have these skills you will be prepared for whatever the future may create.
