What can I NOT do with a felony?

ALRIGHT! I have a dumb question that probably has an obvious answer, but I don't know so I'm hoping a few of you can help me out. What are the jobs that you are not likely to get if you have a felony on your record? Career-wise. I did something stupid in my younger years, and it won't be eligible to be expunged from my record for six years. I'm definitely going to have a college degree by then, but I am wondering what career choices I should go ahead and cross out so I don't waste my time when picking cles/career paths. (for example, I heard if you are a felon, you can't be a cop, etc. etc.) Thank you!
