The 47th law of 48 law of power by Robert Greene says donot go past the mark you aimed for. In victory learn when to stop.
The moment of victory is often the moment of greatest peril. In the heat of victory, arrogance and overconfidence can push you past the goal you had aimed for, and by going too far, you make more enemies than you can defeat. Do not allow success to go to your head. There is no substitute for strategy and careful planning. Set the goal, and when you reach it, stop.
