Ups and Downs of the job
The best part of my job is being a part of something unique. For instance, the engineers that worked on the Pathfinder rover got to sign a plaque that was placed on the bottom of the vehicle and which is now on Mars. I enjoy thinking about the day when someone like you will go find our rover on Mars, turn it over, and see my name.

The worst part of my job is that on almost a daily basis, I am faced with the fact that I'm really not that smart. I am constantly in awe of the people with whom I work. Many are just naturally brilliant. Some are loaded with decades of experience. But all the successful people I work with have one thing in common: they all work hard. And hard work is an incredibly powerful equalizer between the ordinary and extraordinary intellect.
