When I was president of the company, I said, 'Okay, I can do this - piece of cake.' Then when you are the CEO, the responsibilities multiply enormously because you worry about everything.

If you fast-forward through the years, there was a period of time when there was too much debate inside the company about the significance of e-commerce, there were leaders who believed it would never be any bigger than the catalog business, there were leaders that believed it would never be profitable.

Be a great teammate - you learn how to lead, you learn how to influence by the way you interact with your peers, treat them well, help them, help them do a better job.

Good business demands tough decisions based on rigorous analysis and unwavering follow-through. Emotion can't really play a part. The challenge we all face as leaders is to let the feelings churn inside you but then to present a calm exterior, and I learned to do that.

The distance between number one & number two is always constant. If you want to improve the organization, you have to improve yourself and the organization gets pulled up with you.

The one thing I have learned as a CEO is that leadership at various levels is vastly different. As you move up the organization, the requirements for leading that organization don't grow vertically; they grow exponentially.
