At least you enjoy a clean environment. You don't know how many people I've been around that are too lazy to clean up after themselves and just let clutter pile up. If it's your own personal room that's one thing .. but some of my best friends leave their entire apartment that way. It's really .. "tacky" for lack of a better word. When they have guests, they have to push things off the table to make room for people. If I have some trash to throw away and ask "Where is the trash can?" they just respond "Just set it on the table - it's no big deal."

I'm a .. clean person. I'm not a "neat freak" by far but after enough time being around my own clutter, I get sick of looking at it and begin to clean it up until my room is perfect. Sometimes I'll randomly be in the mood to clean house as weird as that may sound. Most people that come to my house always say "Wow your room is spotless" but honestly it's just .. more organized and clean than your average bedroom. Not my fault people are messy lol.

Haha, I'm probably somewhat less of a neat person than you, my areas are usually not spotlessly clean, because when I get busy I will leave stuff around in my areas, then I will clean it all up and have everything organized.
Things really worked out this last semester because of how well organized and neat I was. It does annoy me to a bit when people leave messes around, but if it's their own house and they have no roommates then they can do what they like in my opinion.

You would be horrified if you saw my brothers room.
