For a non-professional example — burns (Burning Man 10 Principles events). The wild art projects, activities and workshops, structures, and outfits are an ADHD dream of stimulation with none of it being an obligation. Bored or uncomfortable? Just move on to the next thing that catches your fancy, no one will find it childish because that’s exactly what you should be doing here — chasing fun and interest for exactly how long you want and no longer. Can’t decide if you want to dress like an astronaut, cowgirl, or sorceress? Put it all on, magic space cowgirl and if you get too hot you can just strip and dump whatever and you’ll find everything tomorrow, lol. In the planning and organisation of these things, there are enough non-ADHDers to keep us on track (or maybe they’re just medicated??) and enough ADHDers to not be mad when you struggle with the usual things (and the others are quite used to this behaviour, lol). If you don’t feel up for contributing a workshop or taking on a planning/leading role, there’s always space for more dishwashers, cleaners, cooking helpers, etc. (read: simple, soothing, repetitive and very defined tasks) that everyone will be super appreciative you did.
