Loftwings and Demons

A concept that I think is generally applicable for whatever you might be trying to do is that knowledge is power. While it's true that knowledge by itself can accomplish nothing, knowledge combined with action is much more valuable than action without knowledge. Action without knowledge has no more probability of success than random chance, but action informed by the right information can make success nearly certain. At the very least, even if the actions you can take are very limited, knowledge can make your actions much more effective than they otherwise would be.

At the same time, we must typically act with incomplete knowledge, since we have limited time to act, sometimes very limited depending on how time sensitive a given situation is. So it's very important to be able to accept one's own fallibility and be willing to correct future actions, and to always be trying to improve and question our understanding of the world.

I think this idea is important for improving at work skills, life skills, hobbies, and activism, among other things.

If there's one thing I've realized, it's that there will always be value to learning things for as long as I live.  Not only will I never know everything, I won't even know all of the important things.  And not only that, but to continue to aquire knowledge is not merely to be writing new information into my mind, but to constantly be overwriting incorrect knowledge.  I have to realize I'm wrong, again and again and again, that my understanding is too simplistic, that it always will be, and yet, at the same time, I must not doubt myself too much.  To lack confidence without good reason opens one up to as much error as to have confidence without good reason.  The only difference is who is determining what those errors will be.
