Charles says, "If you don't get wiser as you get older, then you just get older." The core of this book is about identifying our mistakes, learning from them, and not repeating them. Charles Grodin, a very funny individual who has appeared in movies, television and currently is on WCBS Radio every day, has asked his friends — from Robert Redford, Paul Newman, Shirley MacLaine, Alan Alda, Regis Philbin, Ben Stiller — to share sometimes very revealing memories of the biggest mistake they've made. This book offers intimate insights into dozens of celebrated figures' lives.
