No, you'll make money at your long-run average rate. Which over a large sample you will anyway, and your losing sessions will average out to offset your winning sessions.
You'll just play less hands. And worse, you'll play far more of your B game than your A game, as you'll quit early when you're running hot, and keep on trucking when you're tilted.
Remember, when you play poker what you're looking for is for your moves to have a positive expected value
over the indefinite times you will repeat them, not for them to win you money now. And your long-run EV, if your play is solid, is gonna be slightly positive with usually huge upswings and downswings. The results of one hand or one session (or even one month) matter none.
