"When I discover something great, I love to share it," Oprah says in O's Best Advice Ever!: Make Over Your Life with Oprah and Friends. And she does just that in this collection of advice from such favorite O magazine interviewees as Tyler Perry, Tina Turner, and Jerry Seinfeld. Also included are columns from past issues that still resonate: Dr. Oz's tips on staying well all winter, Martha Beck's strategies for tapping into your creative right brain, and Adam Glassman's figure-flattering wardrobe fixes. The ultimate reference book for living your best life.
