1. Carnegie series is very good! It vividly analyzes people's psychology with a kind and plain tone, and guides you how to resolve the knot and face life positively.
2. George Weinberg's book How to Change Yourself. This book is published by Friendship Publishing House 1989. Not thick, but absolutely practical! It is not a general story telling and analysis, but a simple rule to change yourself in all directions. It is a book of technical psychology.
Carnegie's books may be reprinted in every period, and may be found in bookstores.
The other one can only be found in the library or bought online.
