What do you do with your winnings that are in excess of your bankroll?

Meaning: you've set aside $50,000 as your bankroll. You play a store and earn $2,000.
What do you do with the winnings? Do you increase your bankroll or do you keep it for whatever it is you spend your money on? And what are your goals in playing?

I understand this is highly subjective, but that's what I'm looking for... ideas.

Right now I'm essentially playing with no bankroll. I've got $500 disposable every two weeks. I play with that expecting to ruin. I've ruined in less than an hour, or had +1,800 weekends. I take my winnings out to pay down my high-interest debt, which was the purpose of learning to count. Now that I'm almost done with that, I'm figuring out what sort of bankroll management I'd like to use.

I'm looking for ideas, so I thank you in advance.
