What I've done when unemployed: work out, apply to stuff (duh), set up resumes to apply to stuff when relevant stuff appears, collect random certifications, volunteer (possibly making use of the certifications), spring cleaning, donate useless stuff to Goodwill, take that camping trip with friends, read, write stuff, attempt to learn a new language, listen to or watch one of the Great Courses from my local library, have my friend who cooks all his meals for the week or month ahead of time come over and teach me to perform such magic, finally bother to use my gift cards, make a list of things I need and want, go to dollar day and half off everything day at Goodwill with my list of things I need and want in hand, agree to watch kids or pets or homes, put together a gingerbread style Victorian dollhouse for someone who bought the kit and never got around to it, help friends move, try out those workout videos, review my emergency kit, check expiration dates on everything, any repairs or upkeep I've been delaying for "when I find the time."
