Honestly, give it a shot yourself by downsizing.

Get rid of stuff like crazy even if you have to give it away for free. If you haven’t used or worn it in 6 months, you could probably go without it.

If you search Minimalism on YouTube you will find a deep rabbit hole of online organizers with tons of tips and strategies.

Lastly, stop accumulating stuff. Let people know the best gift for you is no gift. Don’t buy stuff because it’s on sale. Don’t pickup stuff because it’s free. Don’t buy cheap stuff. If you need something, research the hell out of it, even if it’s something as mundane as a frying pan or kitchen knife. If you do it right, you’ll only need one or two, and they should last for life.
