I won't propose to speak on behalf of others but in my case whenever I feel a sense of pride or accomplishment for something I have done, whether that be here at work or in my personal life, I certainly try and take a moment to acknowledge in my mind the many people, some of whom I have no direct connection with, who have played a role in my success.

As the child of immigrants who sacrificed a great deal for the opportunity to come to the US and as someone who grew up poor, not particularly bright, and with no formal education beyond that of high school, but who now has the opportunity to work on hardware that is launched into space, I always try and maintain a sense of appreciation for the country, and its people, that I now call home.
