I re-chose all the items in several drawers (i.e., emptied them out, handled/examined everything, and sorted it into keep/donate/discard piles). This always feels good, and is my default "do something productive" task if I don't have anything specific to do.
Did my laundry.
Remixed a song for an old friend in Australia.
Right now I'm halfway through trying to replace the rechargeable battery in an old cordless razor. Works great except battery is 5 years old... hopefully can just replace the battery!
Played a bunch of What the Golf? <-- amazing game!
