But there are couple things in your post that makes me think you might not quit. First one being the fact you knew for sure. Instead embracing the fact you had luck you went with that. This means you will have these "you know for sure" -hunches in the future too, and since they are sure bets, you might as well just take them. After couple of wins you'll forget that there's a real probability to lose.

I once met a man in a casino who told me that he won $50k from a casino years ago. He quit gambling for a while and spend it on luxury. I congratulated him and imagined what i would have done with that money. He stopped my train of thought and said that at that moment, he didn't realize it was his biggest loss on a bet. What he meant was that human mind isn't build to understand probabilities. He left the casino not thinking he was incredible lucky, but thinking "that was easy". With that mindset he wanted to do it again later in life and failed, so he doubled down and eventually lost more then that 50k. Just because he realized it's possible to do it again, he didn't understand the probability of it happening again.

I am not saying that this would happen to you, i am asking you to realize to remember that this is for fun and luck is involved. Don't bet your house for "being sure". As long as you bet what you can lose you'll be fine.

Anyway, have fun with the money, you earned it.
