What kind of money brining activities have you developed based on what you own and skills you have?
My spot welder and electronics background has brought me plenty of income based on analyzing and rebuilding battery packs and doing small electronics teardowns/research/etc. Though, uh, the hourly rate for my blog work is...
mutter mumble handwave divert. It's a long term investment, though. :)
I am thinking of activities that are built around assets and skills that most people have. What have come to my mind so far is uber driving, Airbnb and being a tourist guide (using one of those apps for travelers finding local guides). Any other ideas?
Oh...
"Stuff most people can do with stuff most people have" is not a good way to efficiently earn money, because most people can do it.
Focus on the esoteric stuff. I'm pretty much "the" aftermarket ebike battery pack rebuilder for North America at the moment.
