Benjamin Zander has conducted the Boston Philharmonic Orchestra for twenty years; he is also artistic director of the music programme at Walnut Hill, a high school for the performing arts in Boston. As a writer he co-authored The Art of Possibility: Transforming Professional and Personal Life. Talking to headteachers at a conference organised by the National College of School Leadership he explains why we should stop listening to the negative voices in our heads and give ourselves and others an A-grade. He urges people to think positively and be open to possibilities. He argues that we spend too much time and energy being weighed down by negative thinking and downward spirals. The secret, he says, is to try to live in possibility - and not to take yourself too seriously.
