One of my favorite teachers is Oprah Winfrey. She teaches me lessons that always make me STOP TO THINK, and her podcasts are no exception. Brief, insightful lessons where people share their insights on life. I am left thinking about the lessons for days, and I inevitably end up sharing them with others. Listen to them while you exercise or drive to work. My favorites include Brian Grazer, will.i.am, and Stephen Colbert. Start with one of these and you will be hooked!
