type A personality
I normally get called something starting with "C", so this might be an upgrade ;D
It is partly therapeutic of course, but I think that it is more than just the process. When things are in their places, daily life feels better. I think it is like driving a freshly washed and vacuumed car.
Treating time like a very valuable resource (not all personality types do that naturally)
Have you ever wondered why it isn't just inbuilt into us all?
