Berg,
I'll have to complete the post I'm working on, but here's the really short answer:
In both cases, I took a brutal approach to jettisoning* stuff; with my office at work, equally important was a frank evaluation of my filing system and a housecleaning there as well. Now my desk is uncluttered during the day, and empty when I leave at night. My clothes closet is now neat and tidy.
And… sadly enough, I didn't take "Before" pictures in either case. But I can write about the process and what worked.
*By jettison, I mean: give away, donate to Goodwill, or simply throw out. One tiny example: I must have had 50 tee shirts (running, Harley, general) stacked on a shelf in my closet. Great – only problem, I hardly ever wear tee shirts! I how have less than 10. Frankly, I'd just gotten sloppy.
