In Attitudes of Gratitude, M. J. Ryan teaches readers how to unlock the fullness of their hearts and lives through the expression of gratitude. “Gratitude helps us to return to our natural state of joyfulness,” she writes, “where we notice what’s right instead of what’s wrong. It makes us feel complete, that we have everything we need, at least in this moment.” In her introduction to this 10th anniversary edition, Ryan recounts current research that bolsters her original thinking—people who practice gratitude on a daily basis are, by and large, happier, healthier, and more effective in the world. She also shares with readers brand new, top 10 gratitude practices, which readers of the first edition and people she’s taught and counseled over the years have provided to her. The concept of this book is very simple and very profound: “Gratitude creates happiness.” It’s a fact of life (and science as it turns out). Plants create carbon dioxide and gratitude creates happiness.
