Perhaps it was no mistake that a month before Oprah announced plans to end her wildly successful talk show, she released 'Dream Big! O's Guide to Discovering Your Best Life.' Was she signaling plans to pursue another big dream of her OWN (the Oprah Winfrey Network)? Whatever the purpose or the timing of its release, 'Dream Big!' is truly inspiring.

"How fantastic would your life look if nothing were holding you back?'' Oprah writes in the introduction. "That's the million-dollar question, and we're here to help you answer it with 'Dream Big: O's Guide to Discovering Your Best Life.' With more than 75 articles drawn from the pages of O, The Oprah Magazine, this best-of-the best collection of inspiration and advice gives you our recommended daily allowance of breakthroughs, insights, and laughter -- and of course, for all of you big dreamers, a triple dose of 'wow.' "

As always, Oprah encourages readers to dream big! The article, 'Great Moments in Self-Esteem,' is a reminder "that you're already far more fabulous that you think,'' she writes. 'Urgent! Urgent! Or Is It?' brings to the fore irrefutable evidence that it really is okay to make room in your world for the things that truly matter.

"I've always believed that becoming your best self involves looking beyond yourself; so this book also includes stories -- you'll want some tissues handy -- about everyday heroes and the extraordinary things that ordinary women can do when they put their minds to it,'' she writes. "Finally, you'll get to meet some of the people who have expanded my own horizons: Eckhart Tolle, who has taught so many of us so much about freeing ourselves from unhappiness; Denzel Washington, who brings such passion to his work; and my dear friend Maria Shriver, whose life is a shining example of the importance of following your heart.''

Oprah Winfrey knows all about following your heart. It's how she's made a living. And the world is eagerly awaiting her next move. 'Dream Big!' is Oprah's story. It is our story. It is the story of every man and woman who dares to dream big. Pick up a copy for yourself and a friend. It's a great holiday gift.
