Stationary drawer - stamps, envelopes, pens, batteries, tape, scissors, glue (both scotch and parcel).
Maintenance stash with spares of every lightbulb in the house. Basic tool kit. Tube of polyfilla and trowel, some spare paint for touch ups/quick repairs.
One spare shampoo, conditioner, facial wash, deodorant, etc. The stuff I NEED on a daily basis. Order replacements as soon you start using the spare.
Coloured towel set per person. This one is a new one for me. I like Ikea's.
Hooks everywhere. A big shelf in the utility room.
I do at least one load of laundry most days so it doesn't pile up.
Similar to a PP, I throw out all my socks and underwear every two years and buy new ones.
Buy birth control pills online and in 6-month packages.
Deal with mail straight away, i.e. record appointments, pay bills, toss away or file same day. Saves a LOT of clutter.
Swapped to a GP clinic that has a daily walk-in clinic, rather than the closer, much harder to book GP.
