Having Secong Thoughts About the Air Force?

I signed up for the Air Force this week. However, I'm not sure If I made the right desicion. To begin my story, I'm 25 years old and I'm a senior in College. I'm graduating this December with a BBA. I applied to be an Officer, but I scored low on the AFQOT, so I enlisted. However, when it came down to pick my 5 jobs choices at the MEPS, I was not happy with the job list. Most of the jobs I qualifed are in the Electronics area since I happened to score high in this section. There was only one or two jobs related to business/management. I don't know what to do. I'm in the DEP. What would happen If I end up not liking my job in the Air Force? I heard I could be thrown to jail for unsatisfactory perfomance and that I could have my pay check cut for months. On top of that, I heard I could get an dishonorable discharge which could affect my career in the future? I don't know If I should continue the process.Please give some advice; I have 2 or 3 months left. Thanks for your honest advice.
