Pay attention because Gus's story may be your story. I've found that engineering is a self-selected profession. As a teenager, I was one of the best students in math and science in high school, devouring calculus problems and differential equations. At 23, I found myself graduating with a B.S. in Chemical Engineering in the top three out of a class of sixty students. I looked to my manager and senior engineers for guidance and direction.
Someone thinks they have twenty years experience.
But, it's really one year of experience, doing the same thing for twenty years. I wanted something different, not sure exactly what, but something different. I believe I was looking for the excitement of a challenge, the same kind I had when I took calculus for the first time. My first job after grad school was the exact job I was looking for. I worked twelve hours a day enjoying every single minute.
