I've tried to cut down on the amount of hobbies I have and partake in, mostly because I have too much stuff but also because I have limited time to devote to all the various hobbies I'd like to have (I really need to be retired to do all the stuff I want to do!).

Ideally I'd like to keep all my hobby stuff for each hobby contained in one stackable crate (the type made from plastic with and interlocking lid) or a comparable size cardboard box, but I've realized that for my 'main' hobbies that's impossible. Stuff for RC cars (which is also a side job), DVD cases, camping stuff, etc., all are way too numerous and bulky to be contained in just one crate, but for other hobbies like bicycling it's fairly easy to put that stuff in one crate (apart from the bike, of course).

Doing stuff like buying games off Steam helps keep the physical bulk down, but I still have bookshelves of books, plus lots of things I've recently unpacked that I will sort into piles: Keep, Give Away, (try to) Sell.

One thing I've taken up recently is building various bits of garden furniture from pallets taken from my workplace: album of pictures of a Bar/garden table, a bench, and long bench made from pallets
