It seems all I do nowadays is work, be grumpy or read. Usually if I'm too grumpy to do anything I just sleep early, but I can't physically sleep enough for my mood these days.
Your methods will probably not work for me, but I think this might get my head working on ideas.
Besides that, I bet others will find some use for your ideas too.
Gardening in the spring and summer. Smoking half of my harvest during the fall and winter. (Plus usually enough veggies to usually have surplus to spread 'em to the neighbors I know will take 'em bc I'm anal about keeping my soil well fed and well tilled, so the yield is usually p good.)
