21. Facebook – Facebook swap shops are great for selling things locally. It’s like CraigsList, but a little easier. You simply search for swap shops in your area and ask to join the group. Once you’re in, take a picture of the item, write a quick description with the price and post it. It doesn’t get much easier than that. You can generally expect to get about what you would get at a yard sale, maybe a little more.

I wrote mostly for magazines, and I had to rely on snail mail to send out drafts and queries. I’d wait weeks for a response from my editors. Not many people had the patience for it, and few stuck around long enough to ever start earning a real income from it.

Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt).

Take good pictures. Some of the options below don’t require you to actually take the picture and sell the product, but for the ones that do, make sure you take a clear picture that makes your product stand out from the others. If you’re going to be taking a lot of pictures, set up a small “studio-like” area in your home with a backdrop and proper lighting to really make your pictures come across as professional. And of course, you’ll want a good camera too.

My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
According to Getaround’s estimates, car owners that routinely lend out their car can earn “$1,000s per year actively sharing your parked car”. Considering there is no effort needed by you, it’s a pretty good way to make money. That being said, your car will likely depreciate a bit faster by virtue of lending it out to other people. If you have a big car loan or are underwater on your loan, putting your car on a site like Getaround might not be a great idea.
