I've had to learn the hard way with stocks. I cut my teeth in the early 2000's when I was in my 20s. I started off playing big board stocks and got sucked into pennys. I lost Ks and now back for try two much smarter than before.
I measure the orbits of asteroids for the Minor Planet Center located at Harvard. I work in the NASA Education and Public Outreach Program, and the University of Alabama at Huntsville in an effort to help students better understand the universe.
