I do. Routine weekly chores, life admin, house and garden upkeep for mine and parents, bike maintenance, things for friends and family, etc. – it all goes on a few lists. I use an app on my phone, syncs to the web version on my computer. I have something completely separate at work for work stuff.
I don’t think most people have one though, and they manage just fine. Even people I know with way more complicated personal and work lives than mine. They forget some things but do them eventually, never get round to others, get chased and reminded about things, or someone else does it, and it’s all ok. Their house hasn’t fallen down, the aren’t in trouble at work or with the wife for not putting up those shelves she bought last year. It appears that forgetting is an useful tool for not wasting time on unimportant stuff or stuff they don’t really want to do but should.
Do you have one?
