Interesting
I hate working in a messy environment. And if I need to stimulate my creative side, I don't sit at my desk. I either go outside or to another environment completely. I use my patio for that type of thinking often and even consider it an alternative office. That said, I can really make a big mess; I can't stand to leave it that way.
I think talking about "creativity" is interesting. How do you even define it? For example, my husband is a very neat and tidy person. And he can look at just about any physical thing and figure out a way to make it work better. He'll repurpose it, redesign it, add something, take something off--it happens without him even being aware of it. He has a vast supply of miscellaneous "parts" that, frankly kind of scare me. I don't ask questions. Needless to say he can fix just about anything, saving us many thousands of dollars over the years. I find this phenomenally creative, yet incredibly practical.
And there's a limit here. Years ago he hung a long tool holder on the garage wall. To my eye, it looked like it sloped down about 6 inches from left to right. To HIM it was great--because he had used a level and it was perfectly level (the garage ceiling wasn't). So that's where I come in--sanity check on "perfection".
For those of you who may be married to a person like my husband, you've already recognized I've got an engineer.

Probably wouldn't fit the standard definition of a creative person, but he sure fits mine!
