True! I've had that feeling myself when I started saving everything to pocket.
So I created a few "self constraints":
I don't save articles that are "current news", this decreases the list significantly and takes the timing pressure off from achieving "pocket-zero".
I only save articles that interest me regardless of the timing.
I also use another "trick": for resources that reference other things I would like to read in the future (articles that mention authors or books) I send them to pocket > mark as favourite > archive. Then when I finish reading my current book of choice I go to the favourites archive and pick through what I want to read next.
