In the movie "The Other Guys" Allen Gamble treats his beautiful, sweet wife terribly. He criticizes her food and her looks until she eventually throws him out.
Later, Allen admits that he is not nice to his wife and criticizes her because he knows that he is not worthy of her. He tells her that he won't admit to how wonderful she is so that others will not want to take her from him.
Life lesson: Treasure those close to you or you'll lose them.
2. Fly, even if you're a peacock
Terry Hoitz tells his captain that he is a peacock and just wants to fly. Others laugh at him, because peacocks don't fly - at least not well.
However, Terry doesn't care. He wants to make the best out of his circumstances and flaps his wings.
Life lesson: Even if you can't fly well, take a running leap and throw yourself up in the air anyway.
3. Encourage others
A businessman in the movie climbs out his window and threatens to jump. Allen and Terry go to the scene and attempt to dissuade him from jumping. However, they're honesty ends up making the situation worse as Terry says "We all know you're a scumbag and no one cares about you."
Life lesson: I don't think honesty means telling everyone everything that's wrong with them. When you can't think of anything good to say, don't say anything at all. Try to encourage each other by finding the good in everyone.
