I would recommend this book to anyone who wants to understand his or her behaviour in situations.

The "A-Ha" feeling you get when you start reading it comes when you understand why so-and-so makes you feel small or angry and why certain situations make you start playing some game.

It discusses the basic terminologies and vocabulary needed and then goes on to discuss in different social contexts and developmental contexts the application of Transaction Analysis.

This is not just a vague psychology book like Freud. It is extremely practical and insightful.

An outstanding self-help book discussing human behavior based on transactional analysis, in an easy to understand language while still technical.
