This Sunday, Oprah is interviewing author Sarah Ban Breathnach about the lessons she learned about money, gratitude and herself after becoming a best-selling author. Tune in at 11/10c!

Before then, Sarah shares 10 simple truths that can start a positive transformation in your life. Which truth most speaks to you? Share it below in comments.

1. Gratitude is the most transformative force in the cosmos, because gratitude is love. Sarah says, "When our hearts are broken, we don't think we have much to be thankful for. We don't have to be smiling when we say 'Thank you.'"

2.  Your happiness increases the happiness of everyone who knows you. "We have so much. All we have is all we need. All we need is the awareness of how blessed we really are."

3.  Whether we live passionately or not is a choice we make. When writers write, the most important emotion is conveyed between the lines. "I want to live in between the lines, where the depth is."

In an encore "Super Soul Sunday," best-selling author Sarah Ban Breathnach tells how she achieved multimillion-dollar success and lost it all. Watch as the Simple Abundance author sits down for a conversation about finding your true self—a talk she says she can only have with Oprah.
