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

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.

Business education must constantly be changing and being updated to improve the quality of the student experience. On line courses will be a key part of supplementing course offerings and providing opportunities for life-long learning. Like any industry, business schools must continue to think and re-think how they add value to students and create thought leadership.

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!

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

We have all had injustice happen to us. It often shapes our failure narrative. For example, maybe you were fired and not you don't trust colleagues as easily in the future. You may not overcome injustice but you need to be aware of how it affects you today. You can't avoid injustice but that doesn't mean you need to be a prisoner of it.

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.
