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.

Reaching your potential is a disciplined process. Like losing weight or getting in shape - there is no final destination and it requires you to dust off atrophied muscles. You have to work at it. If you do, I think you will dramatically improve your leadership.

Authenticity is critical to leadership. That means trying to be yourself - this involves some self-disclosure, admitting what you don't know and being willing to ask questions.

If you're the smartest person in the room, it can sometimes be hard to learn to delegate - the person to whom you're delegating will do the task worse than you would - and it will annoy you!

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.

There are multiple ways to solve a problem and add value. There are seldom right answers. So, you've got to use your abilities to diagnose a situation and use your best judgment on what to do and how to do it. You WILL make mistakes - when you do, admit them and go back and try to fix them. I don't know is often the right answer.

Passion is the rocket fuel that helps you perform at your best. It helps you get through bad days, injustices, hardships and disappointments. It is hard to perform at a high level for a sustained period of time without passion for what you're doing.
