To clean a room

1. It will look nicer. When cleaning, usually a person makes it so that they enjoy the final appearance of the room.
2. You'll find things you've lost. It is easy to lose things, and cleaning often helps one find what they've lost.
3. It'll give you an opportunity to get rid of stuff you no longer need. Whether it is donating those things that are still in good condition, or simply throwing away that of worn out sneakers, there comes a time when stuff has to go.
4. It's a chance to organize. Whatever system you use, being at least a little organized can save you time later on.
5. There will be less places for your pet to hide. Be it a ferret, cat, or some other beast, it can be hard to find them when they hide.
6. You'll be able to redecorate. Redecorating is one of the fun things about cleaning. It can be shifting furniture around, painting the walls, or anything at all.
7. It will make room for other stuff. One of the benefits of cleaning is that afterword, you have space for something new.
8. It gives you time to think. Cleaning a room is often a task for just one person, and as such, it means you can think about whatever you want without worrying about ignoring other people!
9. It can bring back memories. As you sort through stuff that has been lying around for a while, you'll often remember when you received that object. That stroll through the past can make the the time spent cleaning seem short.
10. It can be fun. There are times when cleaning is enjoyable, though don't expect a little kid to ever admit that.
