“Anyone who can't learn from other people's mistakes simply can't learn, and that;s all there is to it. There is value in the wrong way of doing things. The knowledge gained from errors contributes to our knowledge base.”

“Then let’s use this incredible tool God has given us to assess the risks that we face every day. We have the means to analyze risks and decide which are worth taking and which should be avoided. Do you have a brain? Then use it. That’s the secret. That’s my simple but powerful prescription for life, love, and success in a dangerous world.”

“First, we cannot overload the human brain. This divinely created brain has fourteen billion cells. If used to the maximum, this human computer inside our heads could contain all the knowledge of humanity from the beginning of the world to the present and still have room left over. Second, not only can we not overload our brain - we also know that our brain retains everything. I often use saying that "The brain acquires everything that we encounter." The difficulty does not come with the input of information, but getting it out. Sometimes we "file" information randomly of little importance, and it confuses us.”

“By reading so much, my vocabulary automatically improved along with my comprehension.”

“No knowledge is ever wasted.”

“When I was young, I thought classical music was only the background noise for cartoons.”

“Disagreement is part of being a person who has choices. One of those choices is to respect others and engage in intelligent conversation about differences of opinion without becoming enemies, eventually allowing us to move forward to compromise.”

“We did live in dire poverty. And one of the things that I hated was poverty. Some people hate spiders. Some people hate snakes. I hated poverty. I couldn't stand it. My mother couldn't stand the fact that we were doing poorly in school, and she prayed and she asked God to give her wisdom. What could she do to get her young sons to understand the importance of developing their minds so that they control their own lives? God gave her the wisdom. At least in her opinion. My brother and I didn't think it was that wise. Turn off the TV, let us watch only two or three TV programs during the week. And with all that spare time read two books a piece from the Detroit Public Libraries and submit to her written book reports, which she couldn't read but we didn't know that. I just hated this. My friends were out having a good time. Her friends would criticize her. My mother didn't care. But after a while I actually began to enjoy reading those books. Because we were very poor, but between the covers of those books I could go anywhere. I could be anybody. I could do anything. I began to read about people of great accomplishment. And as I read those stories, I began to see a connecting thread. I began to see that the person who has the most to do with you, and what happens to you in life, is you. You make decisions. You decide how much energy you want to put behind that decision. And I came to understand that I had control of my own destiny. And at that point I didn't hate poverty anymore, because I knew it was only temporary. I knew I could change that. It was incredibly liberating for me. Made all the difference.” 

“Class warfare is an artificial division created for political advantage, and it should be rejected outright”

“Today we produce only 60,000 to 70,000 engineers per year, 40 percent of whom are foreigners, while China produces over 400,000 engineers per year. With this kind of technological discrepancy, we will be left far behind in the not too distant future unless we begin to address our educational shortcomings with more than political rhetoric.”

“When politicians prioritize local rule instead of trying to force the whole country to agree with them, I think the pursuit of happiness will be within the reach of a far greater portion of our populace.”

“It mattered not what color your skin was on the outside, but rather what the condition was of your heart and mind inside.”

“Success is determined not by whether or not you face obstacles, but by your reaction to them. And if you look at these obstacles as a containing fence, they become your excuse for failure. If you look at them as a hurdle, each one strengthens you for the next.”

“I practiced in Australia for one year as a neurosurgeon, and my malpractice premiums were only $200 a year at that time. Compare this with the $300,000 malpractice insurance fee assessed on a litigation-free neurosurgeon in Philadelphia today.”

“Rather than trying to control or confiscate guns, it might be smarter to offer free, public gun-safety courses. In countries like Switzerland, every man within a certain age range is required to possess a gun and to know how to use it, and Switzerland has one of the lowest gun homicide rates in the world.”
