Electrical does require some investment in learning. It hasn't clicked for me until recently. I'm in my 40s now. I never quite understood the phases and neutral. Now in my job as a Facility Manager, I've had to increase my understanding of all the systems that make up a built environment. 

Your hands-on learning approach is, in my opinion, the best way to learn. I think that if you take on the finishing, you can experiment. Any mistakes will be useful in learning how to repair. 

I knew a family who all know construction. Dad was a carpenter. Mom helped him out on the job site. All the kids, boys and girls, were put to work as well. It was cheaper than daycare and they learned a trade. It's incredible. They will remodel each others homes as gifts. They have no fear of demolishing and rebuilding because of the experience they got growing up. They have confidence that they can make it look just as good or better than it was.
