+1 I find that a good rule to follow is to avoid "interesting" subject/articles/posts. If it is not also deep, insightful and genuinely educational, avoid spending time on "interesting".
Something that has helped me reduce the collection of components for projects is that I now require that if I'm not going to use it in 90 days I can't buy it. That was in response to finding parts for projects from companies that no longer exist in my inventory of 'things to look into' :-(.
I realized in a world of abundant and instant knowledge, I've been applying the laws of scarcity: "I won't be able to do Y and Z if I spend too much on X". Hence the anxiety to get to the Y when doing X. But it's not going to be a finite list ending in Z. It is an infinite stream and that I have to treat it as drinking from a river vs a cup.
Lately, I've been deliberately giving up on reading about topics, unfollowing people at the edge of my interests and focusing on the areas that are more central. If you look a little bit, you can identify a couple of interests that are stronger than the other. Then it is a matter of eliminating the time spent at the edges.
