Also reminds me of Sandra Felton's book The Messies Manual: The Procrastinator's Guide to Good Housekeeping which had a huge impact on my approach to most things in life requiring organization. I'll one-up the idea of an LRU cache: you can own several pairs of scissors. And the right place for them can be the workshop, the sewing room, the art studio room, the kitchen, and your home office. That one tip has saved me loads of time.
