Sounds like you need to do an inventory of your skills. Or something you like doing. As an example, my daughter liked to sew. She started sewing swim suits for friends and now is full time making suits for the women who do body building. She never leaves home and makes great income. My other daughter makes jewelry out of junk and just got back from Haiti setting up shops there that are now making them for her because she had orders she couldn’t keep up with. There’s gotta be something you could do. With the internet, Ebay, Craigs list etc there’s a market out there for most everything. Woodworking, carving, ceramics, painting, sewing (don’t laugh, I make my own shoes because I can’t find any that fit my polio affected feet) or any other sit down, do it on your own time work.
I’m reading a book about scanning items (don’t have a smart phone but aim to get one) and apps that tell you what that item is selling for on Amazon, e-bay, etc. and if you can make a profit on it, what the author refers to as arbitrage. My 1984 car isn’t cooperating with me (ignition went kaput a month ago) but that might be something I could do.
