“It's not what you know but the kind of job you do that makes the difference.”

“Our country, as well as the rest of the world, faces an enormous threat from ISIS and other radical Islamic terrorist organizations that aspire to achieve world domination. These were the same aspirations held by the followers of Adolf Hitler in the 1930s. Our government must recognize the importance of directly and vigorously confronting these forces of evil. We must not make the mistake of avoiding necessary conflict; we did not get involved in World War I or World War II until we felt that American interests were directly threatened, and this proved to be the wrong choice, though we eventually were victorious. If a vicious enemy that is willing to decapitate people, burn people alive, and even crucify children is allowed to grow with only minor to moderate resistance, it will only become a more formidable adversary in the future. If during this period of tepid responses to terrorist expansion the radical Islamists manage to acquire nuclear weapons, providing for the common defense will take on an entirely new different meaning. The longer we wait to eliminate the threat, the more difficult that task will become and the more dangerous the world will be for our children and grandchildren. We must use all necessary resources to protect the lives of our people. Given the existence of enemies who have a stated goal of destroying our nation and our way of life, one way to provide for the common defense is to hide, which in our case would not be possible. A better option is to try to eliminate the threat, and the earlier the threat can be eliminated, the fewer lives will be lost in the conflict.”

“Some historical revisionists have also attempted to diminish the role of God and religion in our nation’s past. A careful examination of the records, however, makes it quite clear that religion was a very important factor in the development of our nation. In 1831 when Alexis de Tocqueville came to America to try to unravel the secrets to the success of a fledgling nation that was already competing with the powers of Europe on virtually every level, he discovered that we had a fantastic public educational system that rendered anyone who had finished the second grade completely literate. He was more astonished to discover that the Bible was an important tool used to teach moral principles in our public schools. No particular religious denomination was revered, but rather commonly accepted biblical truths became the backbone of our social structure.”

“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.”

“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.”

“GROWING UP changes one’s definition of what is fun — maturation does that, thankfully — so I hate to admit now that as a boy I thoroughly enjoyed throwing rocks at cars. It was a thrill to wait in hiding, ambush the car driving by, and then make our escape. Occasionally, a driver would stop their vehicle and get out to yell at us. But if we were really fortunate, they would chase us. We would run just far enough ahead to encourage them, but when they got close, we would turn on the afterburners of youth, leaving them far behind while we laughed hysterically. Once in a while, the police would come by — usually in unmarked cars — and the chase would be much more dramatic until we reached the ten-foot-tall fences at the end of the neighborhood field. To the police, it must have appeared as if they had us trapped. They had no idea, however, how practiced we were at vaulting those fences. We treated it like an Olympic event, running at full speed toward the fence and then leaping high into the air, grabbing the chain links, and allowing the momentum of our feet to swing us over the top and down on the other side. We would laugh at the police as we ran off, knowing there was no way they would follow us. Today I have great admiration for the police, who risk their lives on a daily basis to protect our lives, freedom, and property.”

“I am fond of saying that if two people think and say the same thing about everything, then one of them is not necessary.”

“When I entered Yale, I had to face two important facts about myself. First, though I could consider myself a smart enough person — I was not quite as smart as I thought I was. Second, I did not know how to do in-depth studying.”

“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. It is clear that guns do not kill people by themselves. Rather, people who are determined to kill will find whatever means are available to accomplish their mission.”

“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.”

“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.”

“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.”

“In fact, it was our second president, John Adams, who said of our thoroughly researched and developed governing document, “Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other.”

“One dark night the skeletons that they had carefully hidden in an obscure closet appeared, grabbed them around the throat, and strangled them.”

“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.”
