In the last month I've fixed (i.e., defrosted) a refrigerator and upgraded (well, sort of) a computer. What's next? Maybe I can get that rusty old lawnmower in the garage up and running. I'll have to wade through the spider webs and snail carcasses first, so it's not something I'm eager to tackle.
Besides, I know nothing about engines. At least with the refrigerator and the computer I had detailed instructions to follow. Whenever my car stops running, I'm within walking distance of a phone. Even if the nearest phone is seven and a half miles away, that's walking distance if you're motivated by a total lack of mechanical ability.
I did take a beginning electronics course at the junior college a few years back. Nothing practical came of it. For the final I chose to write a theoretical paper instead of trying to put my knowledge to use to create something functional. I had two problems with that other alternative: making a working circuit, and standing in front of the class to demonstrate it.
The only thing I was better at in high school than writing research papers was avoiding speaking to the class. Odd, isn't it, that I almost became an elementary school teacher? Not so odd that I failed, though.
