I would agree there are alot of things to most seem boring or unneeded. When we got a designer to layout a septic system for us he used cad. When he came back I understood it rather easily as I had just finished a 16 week class on cad. Though the installer who was giving us a estimate said he need a few days because he would need to give the drawing to his friend to read it. Seem simple to me blue line is sewer pipe red was water. The big square thing was the tank. Though he had trouble with it.
I think to some english and writing papers come easy. That person could write a paper on how a car works but ask them to work on it. I could build a house from the ground up. I have worked on alot of homes and even flipped a few with my dad, but ask me to write a book on how to do it and I am screwed. I guess it is like someone who is a award winning piano player but cannot read sheet music.
