A list of Einstein quotes: You can't blame gravity for falling in love. Once we accept our limits, we go beyond them. We cannot solve our problems with the same thinking we used when we created them. Only two things are infinite, the universe and human stupidity, and I'm not sure about the former. It has become appallingly obvious that our technology has exceeded our humanity. The only source of knowledge is experience. It's not that I'm so smart, it's just that I stay with problems longer. A man should look for what is, and not for what he thinks should be.
