When I started 47 years ago, there were no classes and I had to learn everything on my own through hands on and experience. Thus, I learned very quickly, the wrong way; and, the right way of doing things. And, thank the good Lord above, I never damaged any carpeting or upholstery.
Now, I have given countless operators over the years, "the right" advice because of my background. Thank God!
