Stephen Covey is an American leadership authority who wrote the acclaimed book ‘The 7 Habits of Highly Effective People’ in 1989. The book was named the #1 most influential business book of the Twentieth Century and over 15 million copies have been sold to date! The basis of his book is that there is a gap between stimulus and response, and the key to our growth and well-being is how we use that space. In other words, if we respond to situations proactively, rather than reactively, we can take control of our own lives. The Circle of Influence is a model used to demonstrate this.
