I just want a 9-5 job

I'm a 19 year old in college, completely lost in what I want to do in life. All I know is I want a 9-5 job, sit in an office do paper work, phone idc. Just I want to support my baby, I recently came to the realization that maybe I can't be a physicians assistant (maybe I can) but I want to be able to support him sooner than 6+ years from now. If you guys know any please let me know, I have a meeting with my college counsler on Tuesday to talk about my new Ed plan.
I know everybody says that when you marry young and have children young it never works out. I'm really hoping it does, but I just want to be prepared. I don't like relying on SO to buy me the things I need.
