According to journalist Deborah Norville, there is a measurable benefit to counting your blessings and looking on the bright side. In fact, Deborah says studies have shown that people who focus on showing gratitude get more exercise, are genuinely happier and show differences in their attitude that are recognized by their peers. Jean talks with Deborah, host of Inside Edition, about the advantages of positive thinking, which she chronicles in her book Thank You Power: Making the Science of Gratitude Work for You.

• If you're not the kind of person who focuses on the things you're grateful for, start a gratitude journal. "'Thank you power' is writing down the moments that are good in your life so that you can go back and reflect on them—so you've got this sort of repository of good stuff in your past," Deborah says.
• Gratitude comes from recognizing the small, everyday things that make you happy—an e-mail from an old friend, a random act of kindness.
• Deborah says happiness not only helps you—it can also help your children do better in school.
• "There is no dramatic difference in happiness on the part of people who are wealthy," Deborah says. Happiness and "thank you power" aren't about material things, but rather the moments in your life that have made you feel that life is good.
• According to Deborah, gratitude can help eliminate headaches and allergies and even extend your life. "'Thank you power' can actually undo the effects of stress," she says.
