From becoming an iconic MTV VJ to starring in Dumb and Dumber to being diagnosed with a life-threatening disease, Karen Duffy has been through a lot. But it was only when she became a mother that she realized she had some pretty solid life lessons to pass down. In her new book, she offers advice on building a friend group that is weasel free, finding the love of your life, and determining how much to tip the waiter (as with everything—be generous!). With dry humour and maternal warmth, she shows how we all can learn from unexpected philosophers, even from Bulgarian dancing bears.
