Was going to do either teaching or Mechanical Engineering, couldn't decide. Got a scholarship for engineering at the Univ. of Missouri in Rolla, but found out I was going to be a daddy. Had to support the family, so I joined the military instead.
Did 6 years active, then got out and became a contractor. Still a Reservist. Don't regret it one bit. Got free training and a butt-load of experience, making a decent living. (Still paying for the divorce, but that's another story...)
All things considered, I'm an extremely lucky guy to be where I am.
