And you have to do it every day. If thinking were natural and easy we should all be geniuses. Yet it is a skill, just like skiing and carpentry. We can get better at it if we want to. Learning to ride a bicycle may be awkward and artificial at first, but once we learn how then it becomes very easy and useful.
Computers are nothing without software.
The human brain is just an excellent memory mechanism. It requires software to turn this memory mechanism into 'thinking' mechanism. In this book as software for the mind, Edward de Bono lays out a very simple five-stage structure as a framework for thinking. Much of thinking is a matter of 'directing attention' to what matters. The structure laid out in this book does just that.
