Albert Einstein

“In the middle of every difficulty lies opportunity.”

“We cannot solve our problems with the same thinking we used when we created them.”

“I have tried 99 times and have failed, but on the 100th time came success.”

“In the middle of difficulty lies opportunity.”

“Try not to become just a man of success, but rather try to become a man of value.”

“No, this trick won't work. . . . How on earth are you ever going to explain in terms of chemistry and physics so important a biological phenomenon as first love?”

“I have never belonged wholeheartedly to a country, a state, nor to a circle of friends, nor even to my own family. When I was still a rather precocious young man, I already realized most vividly the futility of the hopes and aspirations that most men pursue throughout their lives. Well-being and happiness never appeared to me as an absolute aim. I am even inclined to compare such moral aims to the ambitions of a pig.”

“I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.”

“Imagination is more important than knowledge, for knowledge is limited while imagination embraces the entire world, and all there ever will be to know and understand.”

“The difference between what the most and the least learned people know is inexpressibly trivial in relation to that which is unknown.”

“Weakness of attitude becomes weakness of character.”

“It is not that I'm so smart. But I stay with the questions much longer.”

“Try not to become a man of success, but rather try to become a man of value.”

“The difference between stupidity and genius is that genius has its limits.”

“Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.”
