Another book - highly recommended

The How of Happiness - Sonja Lyubomisrsky.  This is a 'how to' book as it says on the cover and it delivers what it promises.

She is a psychology professor and writes well.  Scientific basis is excellent and provides multiple approaches.

Well worth a read.

Good book

Zimbardo, the famous psychologist of the Stanford prison experiment has written on the psychology of Time.

The Time Paradox.  Really good and useful.
