A review of the last book I bought, How to Enjoy your life and job by Dale Carnegie, some of the key points of this book are:

Seven Ways to Peace and Happiness

1. Find Yourself, Be Yourself
2. Practice Four Good Working Habits
3. Know What Makes You Tired and What You Can Do About It
4. Banish the Boredom That Produces Fatigue, Worry and Resentment
5. Would You Take a Million Dollars for What You Have?
6. Remember That No One Ever Kicks a Dead Dog
7. Practice Accepting Criticism

there are part 2 and part 3 also in the book so just head over to book and start reading 🙂 its an exceptional book to different aspects of personal life and professional life.
