Hi Dien, de Bono's books Six Thinking Hats & Six Action Shoes are also old but good. Have you read his newest one published just last year? The title is: A New Religion? H+ (plus) How to live your life positively through Happiness, Humour, Help, Hope, Health.

It can be read in less than an hour and those who read it can tell if someone they never met before has read it and know of the principles by the secret signal de Bono describes in the book.

I like his quote You can analyze the past but you have to design the future found at the top of his page at: www.hplusanewreligion.org

Cheers,
