Leadership is a team sport - learning to work with others is a critical skill. This means articulating a clear vision, setting priorities, giving coaching, getting coaching and learning to seek advice from the team. All these activities

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.

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.

I like films about people who figured out what they believed and had the guts to act on it in a way that added value to others. So, there are lots of movies that have characters who did that. I'll pick an odd one - Stranger Than Fiction because I really liked the movie - particularly the offbeat cookie maker. You'll have to see the movie to see what I mean. The movie also reinforces that you can be the author of your own script.

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

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.

It bears repeating: you don't have to be good at everything.
