I was not good in school. I could never read very fast or very well. I got tested for learning disabilities for dyslexia. Then I got put on Ritalin and Dexedrine. I took those starting in the eighth grade. As soon as they pumped that drug into me it would focus me right in.

I had learning disabilities and I couldn't express myself in the written word.

Creative activity could be described as a type of learning process where teacher and pupil are located in the same individual.

What we face may look insurmountable. But I learned something from all those years of training and competing. I learned something from all those sets and reps when I didn't think I could lift another ounce of weight. What I learned is that we are always stronger than we know.

I have never met a man so ignorant that I couldn't learn something from him.

Woodrow Wilson called for leaders who by boldly interpreting the nation's conscience could lift a people out of their everyday selves. That people can be lifted into their better selves is the secret of transforming leadership.

I knew I could not maintain that leadership in open struggle against Moscow influence. Only two Communist leaders in history ever succeeded in doing this - Tito and Mao Tse-tung.

Twenty-eight years in business and you understand the importance of problem solving and the importance of efficiency because if you don't become efficient you don't run a business well and you are out of business. And I think some of those principles could be applied to leadership in Washington.

I had a sense of what leadership meant and what it could do for you. So am I surprised that I am sitting up here on the 62nd floor of Rockefeller Plaza? No.

The United States is the most innovative country in the world. But our leadership could slip away if we fail to properly fund primary secondary and higher education.

There would not be enough talent that's educated developed and ready to take on the next leadership challenge and it would cap our growth. Now we've put programs in place not to have that happen but that could be a weakness.

We should be therefore supporting a larger Europe and in so doing we should strive to expand the zone of peace and prosperity in the world which is the necessary foundation for a stable international system in which our leadership could be fruitfully exercised.

There is no international problem that can be addressed or solved without the engagement and leadership of the United States and everybody in the world knows that its just fact of life. So sometimes I think we could conduct ourselves with a little more humility.

I think President Obama could have handled politics and policies differently. But he has been decisive strong and consistent - important qualities in a president. Mitt Romney is indeed an Etch A Sketch the antithesis of leadership.

It's extremely hard for athletes to accept what's happened to them sometimes. It's hard to be beaten by a small margin and I've spoken with athletes who for years afterward have been tormented by the knowledge that had they done something ever so slightly different they could have been one-ten-thousandth of a second quicker.

And indeed this theme has been at the centre of all my research since 1943 both because of its intrinsic fascination and my conviction that a knowledge of sequences could contribute much to our understanding of living matter.

One could not have isolated this retrovirus without knowledge of other retroviruses that's obvious. But I believe we have answered the criteria of isolation.

When I entered medical physics in 1958 there were fewer than 100 in the U.S. and I could see many opportunities to apply my knowledge of nuclear physics.

I found it peculiar that those who wanted to take military action could - with 100 per cent certainty - know that the weapons existed and turn out to have zero knowledge of where they were.

It's kind of interesting because hacking is a skill that could be used for criminal purposes or legitimate purposes and so even though in the past I was hacking for the curiosity and the thrill to get a bite of the forbidden fruit of knowledge I'm now working in the security field as a public speaker.

There are so many things a large intelligence espionage organization can do to justify its existence that people can get promotions for because it could result in results.

The plan we developed to deal with al Qaeda depended on developing sources of human and technical intelligence that could give us insights into his plans at the tactical level. This is easy to say but hard to accomplish.

Could it be that all those reports coming from our own intelligence that Bush ignored was right all along? Could it be that the UN was right all along?

Louis Freeh said on national TV that actionable intelligence could have allowed us to stop the hijackings.
