Cleaning my room is like getting a haircut…
You see, if you take a point in time that I just (cleaned my room/got a haircut) then it looks nice and neat. As time goes on, my (room gets messier/hair gets longer) at a very steady, but not that noticable rate. There’s never any one point where you can consider my (room/hair) to be “(messy/long)” because it’s so gradual. But the time comes when you can just realize one day that, “Damn, my (room/hair) is so frigging (messy/long)! It’s time to (clean it/get a haircut)!” and then I do, and it’s so noticable… and the cycle begins anew.
