There is no other way to put it.  I have ADHD when it comes to customizing my desktop.
I can't keep it the same way for more than a few days.  Literally.  I change my wallpaper, cursor, icons, WB, and OD+ settings at least 2-3 times a week.  Even when I get a particularly sweet set up that I think I am going to like for at least a week, within a day or two it is changed.  I need to take action and stop it.  It bothers even me (hence I call it a disorder).
But there are just so many great themes out there.  It is like I feel some intangible impetus pushing me forward.  But I am really pleased with my current set up.  I am determined to keep it longer than 3 days.  I am going for a week.  Then, maybe even more.
So am I the only one?  I wonder. . .
