I wouldn't ask anyone to do anything I wouldn't do myself.

The distance between number one and number two is always a constant. If you want to improve the organization, you have to improve yourself and the organization gets pulled up with you. That is a big lesson. I cannot just expect the organization to improve if I don't improve myself and lift the organization, because that distance is a constant.

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.

Every year in consulting is like three years in the corporate world because you have multiple clients, multiple issues - you grow so much.
