I've been retired since this past August. I too got tired of the corporate B.S. and all the mergers and org changes, and luckily I didn't have to take it anymore.
I find myself doing more research, and learning about cars and models than actually building them. Part of it is that my daughters pet occupies my "one day" workshop, and I tire of having to set up and take down every night.
I do spend more time on my models than before, but I get up every week day and after breakfast and newspaper (sic), I go to the gym. Then the honey do list.
I have an inventory of my kits, and a build sheet for most of them outlining my build ideas for each one. I don't always stick to the original plan though.
