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.

Why do leaders fail? Isolation and inability to learn. They are afraid to express doubt, admit vulnerability or seek advice from subordinates. Leaders must actively work to seek feedback and a reality check. They must be open to asking questions and framing issues. As the world becomes more complex and global, the risk of isolation becomes greater. The need for leaders to be open to learning becomes greater. Great leaders will need to ask the right questions and balance inquiry with advocacy.

Business and leadership is about the future. What worked five years ago is unlikely to work tomorrow.

Rather than the word career, I prefer to discuss how you make a positive I pact on the world. This could mean raising your children, professional activities, non-profit work, or various other actions you take that impact others. I have found that, at all ages, people want to be needed and play a role in impacting the world.

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.

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.

The vision must be realistic - it has to be based on clear distinctive competencies. Again, what would the world lose if you didn't exist? A vision is very powerful because it gives you a basis to judge every action you take. Every action should be viewed through the prism of whether it furthers the vision.
