If you had to start over

And play bj as your primary source of income how much would you need as your bankroll? Or if you have a job and play part time how much would u need to quit? For me I think I would need to have 150k-200k and always have 200 or 150 top bets. I don't think you can make your money grow any faster in any other business but I don't know how many times a year you can double your bankroll after a couple years betting at that level.
