Being a "good poker player" isn't the most important thing in the world. My marriage has improved a lot since I realized that.
Seriously though, as long as your not losing money and you're having fun, why quit?
Also, I have a confession to make. I wrote the "Donkeytest." You're actually a donkey if you spent 45 minutes taking this test instead of actually playing poker and maximizing profit.
Guess everybody's a donkey except me! Noobs.
