Success today requires the agility and drive to constantly rethink, reinvigorate, react, and reinvent.

I'm truly saddened to learn of Steve Jobs' death. The world rarely sees someone who has had the profound impact Steve has had, the effects of which will be felt for many generations to come. For those of us lucky enough to get to work with him, it's been an insanely great honor. I will miss Steve immensely.
