I think you can easily separate understanding risk from being disappointed that the risky outcome occurred. It's the difference between knowing (or not knowing) that as a poker player, getting it in preflop with AA vs KK is a great idea, and being sad that your opponent spiked a K on the flop for a $5,000 pot. Now, good poker players do talk a lot about not being "results-oriented" (even if your AA is rivered by KK, you played the hand well if you got the money in before that), and many players will tell you that the way to do this is to cultivate a sense of detachment about money coming in and out. I certainly try to avoid being sad when I lose a big hand; such is life. But being sad isn't the end of the world, so long as you got the money in good and continue to do so.
