Start "caching" your clothes/stuff

"Clothes on chair" is a problem that arises when you don't have anywhere else to quickly store stuff. Computers already have a solution for this. Tailor this approach to your belongings; a tray for keys/wallets (level 1), small basket for common items/accessories (level 2), dedicated drawer for most-used clothes (level 3), etc. This can scale all the way up to your closet and deep storage.

Having a hierarchy and reducing friction for "putting things away" makes it so that everything has its place.
