“The more I learn, the more I realize how much I don't know.”

“I am not more gifted than the average human being. If you know anything about history, you would know that is so--what hard times I had in studying and the fact that I do not have a memory like some other people do… I am just more curious than the average person and I will not give up on a problem until I have found the proper solution. This is one of my greatest satisfactions in life--solving problems--and the harder they are, the more satisfaction do I get out of them. Maybe you could consider me a bit more patient in continuing with my problem than is the average human being. Now, if you understand what I have just told you, you see that it is not a matter of being more gifted but a matter of being more curious and maybe more patient until you solve a problem.”

“From the standpoint of daily life, however, there is one thing we do know: that we are here for the sake of each other - above all for those upon whose smile and well-being our own happiness depends, and also for the countless unknown souls with whose fate we are connected by a bond of sympathy. Many times a day I realize how much my own outer and inner life is built upon the labors of my fellow men, both living and dead, and how earnestly I must exert myself in order to give in return as much as I have received.”

“I don't know, I don't care, and it doesn't make any difference!”

“I don't pretend to understand the universe — it's much bigger than I am.”

“Einstein was once asked how many feet are in a mile. Einstein's reply was "I don't know, why should I fill my brain with facts I can find in two minutes in any standard reference book?”

“I am not more gifted than anybody else. I am just more curious than the average person and I will not give up a problem until I have found the proper solution.”
