How to Stop Worrying and Start Living

| How to Stop Worrying and Start Living is a self-help book by Dale Carnegie first printed in 1948. Carnegie says in the preface that he wrote it because he "was one of the unhappiest lads in New York". He said that he made himself sick with worry because he hated his position in life, which he credits for wanting to figure out how to stop worrying. The book's goal is to lead the reader to a more enjoyable and fulfilling life, helping them to become more aware of, not only themselves, but others around them. Carnegie tries to address the everyday nuances of living, in order to get the reader to focus on the more important aspects of life.

The book's title is satirically referenced in that of the film Dr. Strangelove.
