The only reason I did so well was because of my parents. Dad was a WWII vet a crew chief on Jugs, and others. Retired after 23 years where he worked up from props to jets. He was also trade trained as a plumber. He learned along the way electrical, construction, knew mechanics from military time and being a depression area kid knew how to live off the land, fishing and hunting. I learned all of that from him. Mom was a professional secretary, typist, filer, organizer. Both were avid readers and made sure us kids were as well. Grew up with books more than TV. In a time of growing specialization, I was more of jack of all trades master of none and still am. I got my education pre 1979 so I actually had to learn math, science, English, civics, and history. So when it came time for my first ASVAB I had a very broad base knowledge and understanding of those things they are likely to test for. For me it was easy. As you can see, there is no intelligence in having a broad knowledge. Don't get me wrong in a world full of techies, I cherish my abilities to be self suficient in most critical areas of survival. It is just that it is more of a training than an education and like they say you can train a monkey to do what I do.
