The Conquest of Happiness
Author: Bertrand Russell
Allen & Unwin: 1930
(EN: I approached this book with a mercenary motive, the desire to understand the causes of happiness and contentment so that it may be delivered as part of the customer experience. However, I found it to be more general, and directed to adjust the philosophy of the individual who wishes to be happy unto himself. Which is to say it is more in the nature of a self-help book than anything else, though there is perhaps some useful information to be gleaned.)
