History repeats itself, opportunity doesnt. — Opportunity

"Variant: In the Chinese language, the word "crisis" is composed of two characters, one representing danger and the other, opportunity."

"A wise man will make more opportunities than he finds."

"Who lets slip fortune, her shall never find: Occasion once past by, is bald behind."

"A thousand years a poor man watched Before the gate of Paradise: But while one little nap he snatched, It oped and shut. Ah! was he wise?"

"To attract good luck to oneself, it is necessary to take advantage of opportunities."

"The actual fact is that in this day Opportunity not only knocks at your door but is playing an anvil chorus on every mans door, and then lays for the owner around the corner with a club. The world is in sore need of men who can do things. Indeed, cases can easily be recalled by every one where Opportunity actually smashed in the door and collared her candidate and dragged him forth to success. These cases are exceptional, usually you have to meet Opportunity half-way. But the only place where you can get away from Opportunity is to lie down and die. Opportunity does not trouble dead men, or dead ones who flatter themselves that they are alive."
