Television has spread the habit of instant reaction and stimulated the hope of instant results.

One of the things I like best about 'Biggest Loser' is being around people who are trying to make the right choices. When you feel defeated about your weight and your health, like there's no hope, and you still make the choice to fight for it, to make the change happen no matter what people say or think, that's inspiring to me.

You have to have hope. It's irresponsible to give false hope, which I think a lot of playwrights are guilty of. But I also think it's irresponsible to simply be a nihilist, which quite a lot of playwrights, especially playwrights younger than me, have become guilty of.

If you know that life is basically going to be horrendously difficult, at best, and all but unlivable at worst, or possibly even unlivable, do you go on? And the choice to go on is the only thing that I think can be called hope. Because if hope isn't forced to encounter the worst possibility, then it's a lie.

As I travel across the country speaking about MS, perhaps I can offer others comfort and hope.

I think we have lost our groove as a country. One of the reasons was the attack on 9/11. We got knocked off our game. From a country that always exported hope we went into the business of exporting fear.

People see I am a mother and head of a household. Today in Chile, one-third of households are run by women. They wake up, take the children to school, go to work. To them I am hope.

Hope is a very unruly emotion.

I hope for peace and sanity - it's the same thing.

I think it's realistic to have hope. One can be a perverse idealist and say the easiest thing: 'I despair. The world's no good.' That's a perverse idealist. It's practical to hope, because the hope is for us to survive as a human species. That's very realistic.
