Been there, done that, too. Surrendered my Commercial Driver License (American equivalent) semi-recently because I finally stopped needing it. Tank soldier, later infantry NCO, IT consultant, janitor, truck driver, census counter, meat packer, fast food cook, most recently & most enjoyably, a hotel desk clerk. Bunch of other jobs too. I did whatever I had to/could do to keep the bills almost paid. My mother taught me a very important lesson: pay the rent and then buy groceries first. The rest will take care of themselves if you're warm and dry and can eat.
