On school culture: It's hard to eat something you've had a relationship with.

What we want for our students we should want for our teachers: learning, challenge, support, and respect.

Mentors turn into tormentors if they believe they are always right.

In high performing countries, principals are working with highly qualified teachers who come from the top tiers of the graduation range, who have been rigorously prepared in universities and through supervised practice in schools, and who remain in education for all of their careers.

On being: Arrogance is not the prerogative of the gifted.

Your most memorable students are in your first classes and your last classes: make your last years the finest of your career.

High performance leaders know they have to breathe out when they are coming up for air.
