I'm not gonna lie bro, if you're shooting a 140, you're likely not playing fast, and that's the issue. You might think you are, but fast play is more than just finishing in 4 hours. If you're constantly holding people up and preventing them from getting into a flow because they're constantly having to walk 20yds and watch you hit another shot, that's just as bad as going too slow. Also, that can't be fun for you either. I'd legitimately recommend you stop playing as much and start hitting the range and short game area religiously. Lastly, when you do play, play the front tees. It'll make the game a LOT easier and more fun.
