Afraid of missing out

I have developed this “perfectionistic” mindset that I have to get everything out of a learning source – like a book, for example or a class. I rewatch and reread, take notes, and won’t feel peaceful until I remember every concept, even if it is not required. It’s even with the videos I find on YouTube for my own growth. I begin watching it and am afraid to stop because I am afraid that I am going to miss something important, a piece of information that I will certainly need in the future and will regret that I did not finish the book/video (even if it is boring or I don’t like the content) and what I needed might have been there.

I want to be able to let go of things easily and not feel afraid or anxious about missing out on something.
