It's been a while since I posted (summer chores/projects have eaten up lots of time), and I usually don't like to post long videos, but this life hack video had so many good ideas (and probably a few crazy ones) that I had to share. Admittedly, it moves quickly and I had to go back and watch some of the ones I wanted to remember more than once. I hope you find something useful here.
And one more from the same YouTuber with many different ways to organize things (also quite a long one. You may want to watch these over time).
