My suggestion is two fold. First, personal experimentation on an inexpensive basis. You can buy a lot of basic, cheap materials and tools, and practice specific types of work. You can teach yourself very easily with weekly practice, how to do any type of household work, from drywall to plumbing. Most of it is not difficult, it requires practice and mental effort over time. You get better and better at it. The point is to practice on things you can destroy at low cost, rather than feeling intimidated working on your actual property and fearing causing a big bill via error.

The second is, find people you know that do blue collar work, whatever it happens to be (whatever you're wanting to learn). For example, I know a few guys that work as unlicensed handymen, most of them are quite skilled at what they do, they just frequently work under the table. Pay them for their time to speed up your learning process on specific tasks.
