Our thoughts really do create our lives. They've done a lot of research showing if you're an optimistic, positive person you will be a healthier person than if you're a sad, depressed, negative person.
The pulpit and the optimist are always talking about the human race's steady march toward ultimate perfection. As usual, they leave out the statistics. It is the pulpit's way - the optimist's way.
Rage is caused by a conviction, almost comic in its optimistic origins (however tragic in its effects), that a given frustration has not been written into the contract of life.
I have a habit of comparing the phraseology of communiques . . . noting a certain similarity of words, a certain similarity of optimism . . . and a certain similarity in the lack of practical results during the ensuring years.
I think revolution is always a little bit possible. I think it won't look or sound anything like what we would expect. But I think revolution is very difficult, and I'm not optimistic for any kind of dramatic change.
It's no wonder that America's engagement in the region has strong, sustained, bipartisan support. So I'll be handing my successor a strong foundation - including closer ties with Singapore - on which to continue building, and I'm optimistic that will happen.
Part of what makes me most optimistic is if you look at the attitudes of young people. Across the board, young people are much more comfortable with respecting differences. They are much more comfortable with diversity.

Cuba is actually one where I am more optimistic because of the unique nature of Cuba - 90 miles off our shore with a massive ex-patriot population, now Cuban-American population that still have deep links to the island. There I am more confident that over time that the winds of commerce and telecommunication and travel start shifting the nature of that regime. But that's a small country which has almost a unique relationship to us.
This generation has a responsibility to reshape the world. Start the task even if it will not be fulfilled in your lifetime. Even if it seems hopeless now, never give up. Offer a positive vision, with enthusiasm and joy, and an optimistic outlook.
You have to be optimistic about golf. I mean it's physically demanding, particularly if you're on one leg. But it's psychologically demanding regardless of your physical infirmities. I mean, it's a tough sport. You've got to be disciplined and optimistic. And if you have a bad hole, you've got to be optimistic that you'll do well on the next hole.
I am incrementally a pessimist, but I see the international debate that Edward Snowden has engendered, and I think this is exactly where the discussion should be. So, I would say I'm more optimistic than pessimistic.
