A FORMER Derbyshire schoolboy has dedicated his new book to his teachers.
Chris Paley, who lived in Findern and attended John Port School in Etwall, has written Unthink.
It explores recent findings of psychology, which reveal that people are often mistaken about why they do things and the reasons they give for making decisions.
The book also puts forward a new theory of why humans are conscious and suggests ways to improve the way we interact with people.
He cites the example that when waitresses repeat customers' orders back to them instead of just saying yes, they receive bigger tips.
Advice to politicians is that they should spend as much time on their appearance as on their policies and, if you want someone to fancy you, wear red and meet them somewhere frightening.
Mr Paley said: "Some people are born lucky. They have wealth, beauty or some talent.
"I have been lucky to have great teachers and to recognise it.
"At John Port School there were many, in particular my English teacher Stuart Clarke, whose advice led to this book more than a decade after he gave it to me. For that I am very grateful."
Unthink, a hardback, is priced £9.99.
