Any #poker session you play can be thought of as a series of decisions. The "correct" decision in any spot, such as whether to bet and how much, in principle has an objectively-correct answer. This has some players erroneously seeking perfection.

In the real world, the information you use to make each decision contains uncertainty. You simply do not know the precise range of your opponent, and even if you did, a precise EV calculation in real time is not a feasible goal. Make the best decision you can with the available information, but accept that your goal is to be good, not perfect.
