We have over 50,000 thoughts a day. We accept, question, challenge or discard them. Some tumble around in confusion, become exaggerated and irrational, causing anxiety and mental paralysis. Thinking is healthy but it needs to be managed and channelled constructively. The Thinker’s Pocketbook examines the many different ways of thinking: positive, dissatisfied, creative, lateral, logical, bottom-line, over-thinking and non-thinking, intuitive and magical thinking. There are exercises and examples – all designed to help you improve your mental flexibility.
