With these words from her 2014 memoir “Yes Please,” comedian and Emmy Award-winning actress Amy Poehler encourages us to take on challenges, even when they feel daunting. Poehler — who co-founded the influential Upright Citizens Brigade before moving on to “Saturday Night Live” and later starring in NBC’s beloved sitcom “Parks and Recreation” — is certainly qualified to give advice about ambition. She goes on to suggest that “doing what you're afraid of, getting out of your comfort zone, taking risks like that — that's what life is.”
