That’s what bartending, table waiting, and other under-the-counter occupations are for.
Shhh! I joke about working part-time at Luby's or another cafeteria as a major part of my retirement plan. Flexible hours, discounted/free meals, what could be wrong with that?
I'd also be open to working on a "consultant" basis with a local CPA firm, where I'm paid a monthly "retainer" while doing most of the work during tax season.
