You can't go anywhere these days without running into an article or a book on how to be more positive and upbeat. Pessimism and anger are seen as traits we should do all we can to avoid. But my guest today says that view might be a little too short-sighted. His name is Dr. Todd Kashdan and he's the co-author fo the book, The Upside of Your Darkside. Today on the podcast we talk about the benefits of getting in touch with your pessimism and anger and the potential downsides of too much positivity. And we also discuss what Teddy Roosevelt can teach about the benefits of narcisssim and pychopathy. A fascinating discussion.
