Macbeth, like many of today's leaders, is gripped by fear. Fear of failure, fear of losing power, fear of his wife, fear of retribution, fear of just about anything.  Fear is a very powerful motivator - it keeps us safe when riding our bikes, it keeps us wary when walking late at night. But fear may also paralyse us: from moving forward, from taking a healthy risk, from making a change in our life.  Fear is one of the first emotions we learn to express.
