"There is no excellence in this world that can be separated from right living"
This book is a classic. The author goes into great detail about the 7 key habits that, if you adopt, lay a solid foundation for lasting happiness and success.
The principles are described as guidelines for human conduct that are proven to have enduring, permanent value. Some of the principles outlined in this book had a great effect on me, especially "Begin with the end in mind", which is all about strategic thinking, and "sharpen the saw" which is about preserving and enhancing the greatest asset you have....you.
