'Of one thing in life we can be sure. The quality of our life in the future will depend on the quality of our thinking.' Why are we more prone to be negative? And how can we become more positive, both as individuals and as a society? We need to develop new concepts: some brand new and some slightly different. This book deals with this topic.
