Collector’s fallacy: you really have to work with something to understand it. Knowing about a thing is not the same thing as knowing it.
Collectors don’t make progress.
In my own life, this rings true- none of my bookmarked pages have done me any good if I never opened them. None of the sample packs or VSTs or photoshop brushes are useful unless I go through them and try using them. Saving tutorial videos (or even watching them) isn’t that useful unless I try it for myself or at least take notes. And stray thoughts that I jot down don’t tend to go anywhere unless I go out of my way to revisit them, nurture them, and connect them to each other. At the minimum, there needs to be some learning exhaust.
