I think we can all take this lesson into our daily lives...
"If your enemy is superior, evade him. If angry, irritate him. If equally matched, fight, and if not split and reevaluate."
The Dutch were able to control their emotions, but the Brazilians were getting all emotional out on the field. Pushing, shoving, yelling, etc. Felipe just lost it and got red carded for stomping the shit out of that one dutchman.
Remember, the underdogs can win....Just gotta keep to your cool and not let your ego get to you. Brazil went into the match thinking it would be impossible for them to lose. The media, WSJ, everyone thought Brazil would win.
