I am an electrician with a high school education. All you need to learn you learn from home. The rest is just daycare with rare exception. That qualifier is for Mr. Gerald Hollingsworth, my history teacher who changed my world into something much better.
i have to be honest with you. I have more respect for electricians (hopefully not IBEW) than I do teachers. The older that I get the more respect I have for skilled workers vs. academic geeks. I am an Enterprise Architect (work in IT) and completely fed up with work politics, poor management, and people who do not keep up with technology to do their jobs. I am building a gunsmith business on the side, and maybe in a few years I will be skilled enough to do that full time.
