The way I like to think about it is that whenever you face uncertainty, your actions might seemingly be proven wrong in retrospect, but may still have been correct based on your past knowledge.

That's undoubtedly correct, but I find it sometimes difficult to apply, since there's always the possibility that you could have overlooked important information, or that you are using that logic as an excuse. In poker, different from real life, you always know exactly what you know and what you don't know.
