When I'm paying with a card I hold my wallet until I get my card back. I wrote myself a script and have my dot files on github to make setting up a new machine quicker. Tons of gmail filters. Ian's knot to tie my shoes (I know, doesn't really save time, I think there's an XKCD that shows the break even point on time investments like that). Aliases like 'helpme' that remind me of some Git commands I always forget. Brush my teeth while peeing.

Yeah, mostly stupid little things.
