It was an exciting book.I loved it.Dale Carnegie's proven techniques have helped me to adopt new mental attitude that lead to happy life.If you want to avoid worry shut the iron doors on the past and the future.Live in day-light compartments.And also try to count your blessings-not your troubles.Always do the very best of everything that you can.Try to review this book each month.And also keep a diary in the back of this book showing how and when you have applied these principles.
