What's a "life hack" you swear by that actually makes a difference?

So many"life hacks"out there seem gimmicky or unreslistic, but I've found a few that genuinely help make life a bit easier. For example, I started doing a "10-minute tidy-up"before bed every night.It's amazing how much better I feel walking up to a clean space.

Do you have any small habits,tricks or routines that actually make a difference? I'm curious to hear what's worked for others!
