1. You're lazy. 2. You really don't care what your environment is like. 3. You're a normal kid assuming that you are a kid. 4. You're too busy to clean. 5. You don't know how to put something back where it belongs before taking something else out. 6. You think you'll wake up and it will magically be cleaned by the cleaning fairy...(A.K.A your mom)
I believe it's because you're a perfectionist. Sort of an all or nothing type personality. I mean that in all seriousness too! Your mind visualizes a clean room, but when it doesn't happen, you give up all together. Just my personal belief about hoarders and messy people.
