Esteemed broadcaster, producer, actress and philanthropist Oprah Winfrey confesses she "can't remember!" the last time somebody has told her "No." She then reveals a lesson she's learned about this, sharing, "The most important thing for me, was for me learning to say 'no.' Because I had this whole big thing where I felt like I had to say 'yes' to everybody for everything... The greatest joy I have is I only do exactly what I want."
