> A similar principle in poker (which has many lessons for life in general) is that as long as you keep making the correct decisions, in the long run you will win. If you invest emotionally in the prize you will likely make the wrong decision.

Excellent point. A bad outcome realized through a correct decision making process is painful, but is still a "better" result than a good outcome realized through a flawed decision making process. When poker players go "on tilt" they start breaking their process and it shows in their long run results.

There are few places where this is more on display than in high stakes poker tournaments.
