Without strong visionary leadership, no strategy will be executed effectively.

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!

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

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.

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

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.

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