Bossypants is an autobiographical comedy book by Chicago improvisor and former Saturday Night Live head writer Tina Fey
"THERE ARE NO MISTAKES, only opportunities. If I start a scene as what I think is very clearly a cop riding a bicycle, but you think I am a hamster in a hamster wheel, guess what? Now I’m a hamster in a hamster wheel. I’m not going to stop everything to explain that it was really supposed to be a bike. Who knows? Maybe I’ll end up being a police hamster who’s been put on “hamster wheel” duty because I’m “too much of a loose cannon” in the field. In improv there are no mistakes, only beautiful happy accidents. And many of the world’s greatest discoveries have been by accident. I mean, look at the Reese’s Peanut Butter Cup, or Botox."
