idk about developing a new habit but laundry isn't hard. you just need a laundry basket. The trick is - don't let it get dirty/unorganized in the 1st place. Do it as you go. Little bit at a time. Don't come home and throw a sweater on the floor or socks on the floor. Throw them in a laundry basket. Don't leave a bag of chips on your dresser or water bottles or whatever. Take the 2 seconds and clean as you go. If it starts to get cluttered - then it's just downhill from there. And then cleaning becomes a project - which just keeps getting pushed back and then never done. This probably isn't the answer you were looking for but it worked for me.

And don't be a hoarder. if you have to much stuff it can be overwhelming. Get rid of junk you don't need. If you have shit everywhere it can be overwhelming mentally
