What are your time-saving non-tech life hacks?
I'm looking for things you do in your day-to-day life that save you significant amounts of time.
I shave my hair, and I do it myself.
I don't have to comb it. I don't have to spend time and money going to the barbershop. I don't have to expend mental energy thinking and worrying about whether my hair is messed up (rain, sports, winter hats).
I've been doing that for more than 15 years and the payback has been huge. It's very liberating.
What about the opportunity cost from not looking as good as you might with a nice haircut? ;-)
Just bugging you. Wish I had a nice round skull that looked good with that style.
As far as life-hacks go, I generally seek to run my domestic operations like an OS scheduler - start background things first (get that kettle boiling, get that washing machine running, etc) and then proceed to interactive chores that need direct attention while other things are happening in the background. Keep as many things busy as possible. Buy a Roomba.
