"... when you talk about yourself or talk to yourself or you have that tape running through your head about yourself, try to picture you talking to your own daughter or your younger sister. Because you would tell your younger sister or your daughter that she was beautiful, and you wouldn’t be lying. Because she is. And so are you."
This is obviously pretty gender-specific, but for you guys out there, just replace "daughter" with "son" and "sister" with "brother" and you’ve got yourself a message to take home too.
The entire thing is worth watching, but the quoted part stuck out to me the most. Amy Poehler seems like quite the amazing lady.
