Poker Forum by Poker is Rigged

I was wondering if there is anyone out there who is currently playing poker for a living? I am considering playing professionally (cash games mainly), but I wanted to get some insight into what it is like before I take the plunge. How big of a bankroll do I need? What stakes should I play? Basically, I am looking for any and all information that will help prepare me for my days as a grinder. Ciao for now.
