As an executive, what do you do when your business model is no longer sustainable? Or even scarier, when your business is doing well but you feel you could go bigger—maybe a lot bigger? What happens when you find success but are still chasing a dream?

These are leaders who are unwilling to stand still when those with less ambition would call the job done.
