Yes. When I stopped working, I had credit cards and other bills that I was unable to pay every month.
I worked for some oil companies; in the 1990s I starting working at NASA until the Shuttle program ended; after that, I had health problems that left me unable to work full time. I have been selling collectibles on eBay for several years.
I have always drawn and painted in my spare time for fun, but since I've been out of work I started selling paintings on eBay and I was surprised that they actually sold! Painting and drawing are therapeutic as well as a small source of income.
