Don't expect to be a millionare.
This is 99.99% never going to be in the realm of reality. When you first get out of college more than likely you will get a job. Don’t waste it or mess it up. You want MORE than just a job, one of the wisest things anyone ever said to me was in my college orientation, the Dean said: a JOB is what you could get and you will become it: Just Over Broke. So make sure what you do and whatever career you choose is something you really LOVE don’t waste time with it otherwise. Life is too short. If it’s not a stepping stone to something great, move on.
