There are a number of good books about life.
Some that I found to be good are:
1. If Life is a Game, These are the Rules by Cherie Carter-Scott
Cherie's book addresses various guidlines or "rules" in life. The thought provoking subjects include lessons and learning, satisfaction and gratitude, fair treatment of others, making the most of life, and self inspiration as well as other good thoughts. This excellent book is well worth reading.
2. Don't Sweat the Small Stuff by Richard Carlson
Richards' book is one of several he has written about life and making the most of it. The book has 100 chapters that are one to two pages in length and provoke thought on a variety of subjects, including: relaxation, gentleness, compassion, listening, kindness, giving credit, living life, learning from others, patience, forgiveness, thinking positive, gratitude, friendliness, ubderstanding, and giving. Also, an excellent book.
