If I compare myself to my entire highschool class, I'm easily in the top 5% but I was taking classes with the top 1%. One guy runs a successful law firm, one is an executive at Microsoft, several MDs and at least one PhD. I traveled the world making very good money, had a great time and married an amazing, beautiful women. I'm 41 and could easily retire whenever I want but I enjoy my job. I was the guy they assigned to projects that weren't going well because I could go out into the field and get everything straightened out. 95% of my job was "common sense"; my point was people tend to overvalue "common sense" when specific knowledge pays better.
I also gained a lot of common sense while I was in the Army but that was generally **** all around.
