The opponent won because of his mistake

In sports, in business and in almost everything else in life, the adversary wins, not because he is stronger, but because of a mistake committed by the opponent.
A recent example of this was the fight between Anderson Silva and American Chris Weidman. Even if you do not like or understand anything about UFC, you can easily learn from this lesson.
Eight seconds into the video above, Silva is seen provoking his opponent – something he had been doing since the beginning of the fight. And in a split second, Weidman took advantage of this situation and knocked out the Brazilian. Not only was this knockout the first in Silva’s 38 fight career, but it cost him the world title he held record for since 2006.
If you study the victories of a sport, business, politics or any other area of life, you will find the same thing. The enemy wins, not necessarily because he is better, stronger or smarter. He wins because the opponent slipped up during or prior to the competition. Someone had already said this in a nutshell about two thousand years ago:
Nor give place to the devil, Ephesians 4.27
1^st lesson: Be careful with your mistakes. They are the main reason for your losses.
2^nd lesson: If you want to win, identify your opponent’s mistakes and weaknesses, and take advantage of them. But remember that playing dirty is proof you did not learn the first lesson.
