Let's not fool ourselves, the guy maintains a chip-on-the-shoulder air about him. This is what has allowed him to accomplish so much. And, most importantly (imo), Armstrong's instensity has allowed him to drive the Livestrong foundation to great heights.
Listen to what he says during the recent Schapp interview, he's clearly focused on Livestrong and wants to grow it even more. Whether there's some personal gain mixed in matters not -- everyone wins in the end due to Armstrong's bold approach and hi-energy attitude.
