Let me explain kewlj so there is no confusion: a gambling bankroll should only be a gambling bankroll. Let's say you put aside $10,000 for gambling because you've determined you need $10,000 for your gaming. That's your gambling bankroll. (Singer, by the way, had a video poker bankroll of $57,000 I believe to play his game.)

If you have profits from that gambling bankroll, you can "pay yourself" from it, but you would still maintain your $10,000 bankroll.

If your decide you need a $10,000 bankroll but can't maintain it then you are not winning. As soon as you drop below $10,000 (which is what you determined you need) you are in trouble.

Of course if you think replenishing a gambling bankroll is the sign of a successful player, then go ahead and be that way. But it won't cut it as a business model. In business you have a bankroll for operations and you pay yourself as you profit. If your business can't survive you don't want to tap junior's college fund to keep the struggling business, or do you?
