Sadly we are in an in-between time where it's anybody's guess how to make a living doing practical stuff. I believe in the power of libraries, so that's why I am starting a subscription library. I once knew a guy who could fix anything: lawnmowers, stoves, heating pads, microwaves. He had a gambling problem and was unable to monetize his skills. The big thing is attitude: most people wait for that killer salary class position and/or are already stuck in the salary class and dependent. The number one goal should be to learn how to be poor and how to live well outside the salary class.

As far as skills in the next decade, you might try carpentry, painting, drywall, locksmithing, plumbing. Otherwise known as "the trades". Farming is a bust because the corporate monopolies control almost all farming. Can't do anything in healing because some pharma zombie will sue you, especially if you're a successful healer. If I had time, I would restore furniture and sell it on eBay and Etsy.
