What determines whether you a pro / semi pro player?

[HC5831]

I've been curious how I should classify myself as a poker player. I think I am a semi-pro. Poker suppliments my income, although it now makes up 2/3 of my income. I am a college student. I play 11 hours a week, making $50/hr, for 2200/month at Party Poker $50+5 NLHE SnG's. My sole sourse of income could be poker and I would be able to pay my bills. I am a college student right now. I'm starting to eyeball the $100 tables.

What are your thoughts? How much do you play/make/stakes?
