"You may believe that you are responsible for what you do, but not for what you think. The truth is that you are responsible for what you think, because it is only at this level that you can exercise choice. What you do comes from what you think."
Give all options to the opponent, if you win its historical, if you fight and loose- he is definite to loose next time, if you loose-you can enjoy his happiness even.
The price of success is hard work, dedication to the job at hand, and the determination that whether we win or lose, we have applied the best of ourselves to the task at hand.
