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.

You never do arrive at a destination. You have to work at it and take ownership of the process. What resonates at age 25 is likely to change by age 35 and 45. The process never ends. Realizing this has been a big breakthrough for me.

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.

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.

Step one is to take ownership of figuring strengths ans weaknesses out. It starts with writing them down but, to take ownership, you have got to seek feedback of those who directly observe you - this is scary and uncomfortable for many people. It's no fun to hear negative feedback and most people don't want to stick their necks out to give it to you. So, you have to ask.

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.

Great companies create an environment in which employees act like owners. They do this through clear communication, articulation of clear vision and priorities, coaching and openness to debate/discussion. I would argue that this type of environment helps people to be at their best - and helps the company to be at its best.
