Who knows, but honestly you're probably worrying too much. The human brain is extremely elastic. So read a book, keep a journal, draw a little picture of a house. You'll be okay :)
What the fuck are you talking about? Are you telling me to personally cast the fittings used in my water heater? To hand solder a PCB for my microwave? To machine my own engine camshaft?
Or did you already decide on a response after you read three words and guessed at the rest? In what state, may I ask, did you receive your education?
