Having been in the electrical trade since 1980 I learned a lot by watching other contractors do there thing, plus a little common sense goes a long way.
I grew up on a small farm well it really wasn't a farm about 12 acres. Mom had her garden we also had a couple of horses, chickens etc!!
I have no choice but how to learn how to do thing's myself!!!! I can't afford to pay anyone to do things, plus having friends in other trades helps if I need advice.
Here is a come back for ya if someone asks are you talking to yourself. " Say ya I am the only person I can carry on an intelligent conversation with"
As Doc would say "Good to Go"
