There's a step that leaders need to take; they've got to understand themselves.

It bears repeating: you don't have to be good at everything.

As a leader, it is often better to ask the right questions and listen than to have all the answers.

You're changing, the world is changing, and your hopes and aspirations are regularly being updated. That's why I say this is a life long struggle - for everybody.

I loved my career at Goldman Sachs. I believed in business principle number 1: if the client succeeds, our own success will follow. This principle formed the basis for my career and my leadership style.

Without strong visionary leadership, no strategy will be executed effectively.

There is usually a clock in our heads regarding decisions we make and the course of our lives. Sometimes this clock is helpful in that it get us to move rather than put off key actions. Other times, it creates us false sense of urgency that can cause us to overreact, lost patience and make poor decisions. In raising this issue in my book, I want people to be aware of the clock in their heads and question whether that clock is helping or hindering the quality of each particular decision.
