...until your last penny is gone...
I will repeat what I put in another post a while back:
There are two required skills:
1. You must know how to play; and
2. You must know how to win.
If you know neither, you have NO chance.
If you know how to play but not how to win (and it appears you are in this category), you have NO chance.
If don't know how to play, but do know how to win, you at least have a *chance* of hitting a run of pure, dumb luck and going home winner.
But if you know BOTH how to play AND how to win; you have a reasonable shot of winning reasonably consistently, and winning more than you lose in the long run.
IMHO, your priorities are wrong.
The goal here is not to "play perfectly." You can play perfectly all day long and still lose.
The goal here is to WIN MONEY!
By all means, perfect your skills and play as much as you can to help you win money. But do NOT lose sight of the primary goal: WIN MONEY!
If you persist in your inverted priorities, you will indeed be playing "until your last penny is gone."
