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.

Rather than the word career, I prefer to discuss how you make a positive I pact on the world.

One reason leaders don't delegate is they haven't been sufficiently clear with the team regarding their vision and key priorities - so that the team understands where the firm is going. If everyone is on the same page, it's a lot easier to delegate effectively.

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.

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.

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