I have the same problem with both Netflix and Video Games... Analysis Paralysis.
I find myself paralyzed by indecision more often than not--generally I keep some short games (Tetris, Terra Battle, Crossy Road, etc.) on hand which I will throw on and mindlessly play while I wait to come up with the next larger game to play. That or I just wind up losing hours to Tetris, but that happens sometimes.
In terms of finding new stuff? Rock Paper Shotgun regularly covers small, free games that are if nothing else interesting little experiments to check out. I've gotten in the habit of pulling one or two of those a week to check out--sometimes they're crap, sometimes they wind up being pretty good, and most of the time they get me to go back and explore an older game in my backlog.
