Used to be one of those people who had to watch every single episode or I felt like I was cheating myself somehow. Spent years stuck on the same three shows because I kept burning out halfway through some 200 episode thing with a hundred filler episodes. Then I tried your way with a couple shows and man, it was like a weight came off. I actually remember what happens in the shows I finish now instead of just grinding through episodes like a chore. Some filler is fun and worth it, but most of it is just padding to keep the show on the air longer. Your mileage may vary depending on the show, but cutting the fat got me from finishing almost nothing to actually keeping up with a whole season.
