Hello all (and Happy Thanksgiving BTW!)

I'm relatively new to the game. I'm mastered BS, but still practicing my card counting skills until I can do it in my sleep. I've also read about 5-6 books on the subject by the masters (Wong, Snyder, etc.) Before I got the bug, I have only played occasionally just for fun. Maybe drop a couple hundred bucks a few times a year at the local casino.

Anyways, something I have yet to come across that Im hoping you guys can answer, or at least point me in the right direction. How exactly does one "make a living" playing blackjack? What I mean by that is, at what point and at what amount/percentage do you start using your winnings to "pay the bills" so to speak.

I'm looking for both a mathimatical, maybe industry standard approach, as well as some stories from people that have actually done it.

The reason I am asking is this: I plan on retiring, or at least semi-retiring in the next 4-6 years. I will have more time to go to the casino as well as an actual bankroll to play with. I would like to be able.to supplement my income by about $500/wk playing blackjack.

These are my initial thoughts:

1) Starting bankroll of $10,000

2) $10,000 ÷ 400 units = $25 minimum bet

3) $25 min. bet x 1.68 unit per hour win rate =$42/hr.

4) $500 goal ÷ $42/hr win rate = 11.90 hours one must play to achieve this result.

I know this is all hypothetical but it sounds reasonable to me. Please let me know where I'm right/wrong, if I'm on the track, how my math should be different, and other things I should consider. Please dont flame me, I'm new and this is why I am asking. We all have to start somewhere.

Thanks in advance for everyones input
