No organisational tool has ever worked for me, but I regurarly bump into game-changers for #adhd folks (like Org-mode in Emacs). In my case, I get tired just after finishing setting up a given tool or simply I forgot about using it or I delay updating it to the extent that it's pointless to do anything with it. I haven't even setup anything when kiddo was born. All we have is a shared calendar and secure cloud drive l. I thought about creating lists of important items for travels / races etc, but I haven't ever done that mostly because these things are fluid and keeping the lists regurarly updated feels like a burden.

I don't mind, I don't need a solution, but I'm curious what works for you fellow #ADHDers or maybe you embrace the chaos just like me?
