Electrical engineer Mike Hord says “if you can’t find it, you don’t own it.” Acoordingly, he has organized his portable component kit and tool kit. He has every tray of his toolboxes photographed with callouts and explanations giving you the 411 on everything he carries with him.
Owning an object has a cost, however minor, associated with it. You’ll have to move it if you change residences, you have to keep your kid/cat/ferret/sugar glider away from things you don’t want smashed/pissed on/drug under your couch/scent marked by a weird oily forehead gland, and clutter (IMO) occupies mental real estate we can usually ill-afford to waste. If you’re going to pay these costs, you should take care to keep your gear well organized so these costs aren’t wasted when it comes time to use something.
