I have a number of teeny little income generators that have been running for many years - some for two decades!. They vary in results and are never consistent, but December brought me $195.00 and January is $72.00. Over all the years these things have run, it's at least $10,000 and probably more. It's dumb not to do this.

Now that Medium allows affiliate links, I need to comb through older articles and see where that makes sense.
