i cant have misc files on the desktop. only important shortcuts, recyclebin, mycomputer, and folders. everything else stays in the start menu or in the quickstart bar.
i cant have shortcuts, files, etc in the middle of the desktop, they all have to be pushed to the sides.
i always keep the recycle bin clean.
i dont keep files in my documents, i have to keep them in a seperate folder in the root of my hdd <--easier to find in stead of doing c:/documents and settings/chris/my docs, etc
and i dont know if this counts, but i am always clicking my mouse, just in random places.
also, i have an optical mouse, and i tend to tilt it to the side, so the red light shines in everybody elses eyes.
