“Opportunities multiply as they are seized.”

“Begin by seizing something which your opponent holds dear; then he will be amenable to your will.”

“In the midst of chaos, there is also opportunity”

“The good fighters of old first put themselves beyond the possibility of defeat, and then waited for an opportunity of defeating the enemy.”

“Conform to the enemy's tactics until a favorable opportunity offers; then come forth and engage in a battle that shall prove decisive.”

“If you do not take opportunity   to   advance and reward   the   deserving,   your subordinates will not carry out your commands, and disaster will ensue.”

“He will win who knows how to handle both superior and inferior forces.”
