You learn a lot when you're barefoot. The first thing is every step you take is different.

In the '80s, Ronald Reagan inspired me to become politicized, because I grew up in that era when everything I cared about was under attack.

We have a saying in my house, my kids and my girlfriend. We say, 'Be your best for the greater good, and rock out wherever you are.'

My mother, she made sure all of us were treated the same and had the same opportunity to grow and develop, so that when we left the house, we could fly on our own. And she also knew when we got out into the world, we'd treat others that we came across with that same treatment and respect.

I try to use the attention that I get to help and to serve, and that's really what I'd see as my work - to serve my community, serve the planet, serve my family. And I think a celebrity is someone who draws the attention on themselves, and then it kind of stops there.

Like sunshine, music is a powerful force that can instantly and almost chemically change your entire mood.

I think that fear comes about when there's things in the world that we want to change, things we're scared or angry about, and we can't change them, and so we become fearful; we develop anxiety.

When I first started, my songs were the politics of anger. As I got older and hopefully wiser, I wanted to be part of the politics of answers.

History shows that Americans believe in doing the right thing.

Playing on the streets of Iraq, or in Israel or the Gaza strip, I'd sing angry protest songs against war. People would say, 'Make us clap, make us dance, and laugh and sing.' It really made me think about the importance of happy music.

People worry that gas prices are high and how they are affecting their pocket book. But they want to know about renewable energy. People are really starting to question things, and that's made people look to the future in a positive way.

I drive a hybrid. It's a Ford Escape. That's my only car.

My usual day is I get up around 11 o'clock and do yoga and then eat afterwards. Then I have sound check and play soccer and do running with the guys in the band after sound check, and then do the show and eat dinner after the show and usually get to bed around 3 o'clock by the time we get everybody on the bus and get rolling.

The U.S. has historically been the world's largest contributor to climate change.

I really encourage people to travel so we can see how the rest of the world views our country. That's really important. Secondly, as artists, activists, and citizens who vote, we have to begin to vote from our heart.

Recording in Jamaica is like nothing else. The studios are always closed in America. But in Jamaica, the studio doors are wide open, and there's music blasting out in the street. You can see the reaction of people immediately.

I don't know if music can change the world overnight but I know that music can help someone make it through a difficult night.

I went to the University of San Francisco on an athletic scholarship. I didn't study in high school. I was just there to get by and to play basketball. But a funny thing happened to me when I got to college. I got challenged by the work and the professors.

Traveling to the Middle East and playing music for people on the street, for soldiers, for people in hospitals, and for people who lost their homes, and seeing people open up through the experience of music really restored my faith in music, in art, and in culture to change things.

We would play songs live on stage, and then we'd watch their reaction we were receiving immediately, if people were dancing and singing along. If they weren't, then we'd go into the dressing rooms of the different NBA teams that we were playing in their arenas, and we'd change the songs right there.

The rap community has been singled out as more homophobic than other groups, but I don't think that's right. It's homophobic, all right, but no more so than the heavy-metal community or the Hollywood community or any other community.

When I first started out, I thought it was enough to make an angry song that pointed out the problems of the world.

After a show, I'll get the 16-year-old white kid whose lip is pierced, his head is shaved and his parents hate him, and the young gangster from the screwed-up 'hood, and they say that now they realize there's someone out there who thinks like they do.

During my travels in Iraq, Israel, Gaza, Brazil, Indonesia, Japan, Europe and all over the United States, I have seen and heard the voices of people who want change. They want the stabilization of the economy, education and healthcare for all, renewable energy and an environmental vision with an eye on generations to come.

You get everything you could have ever wished for if you're willing to give that eternal bliss away to somebody else, to give it back.

I have moments all the time when I play.

No life's worth more than any other, no sister worth less than any brother.

In Jamaica, the music is recorded for the sound system, not the iPod. It's about experiencing music together, with other people.

I really believe that, as an artist, my opportunity to help to bring about awakening is one that should come from a personal process that someone has, and not from me telling somebody that this is the way it is.

Music was a central part of my childhood because my mother played organ and piano in the church, and that meant all us kids had to be in the church choir.

Music has the power to bring people together like no other art form.

Jamaica's a country of great dichotomy. On the one hand you have a tourist industry with great beaches and resorts, but on the other you have such great poverty and the violence that goes along with that.

I'm not an idealist. I know we're not going to be living in a world that's peace and love all the time. But we can live in a world where we kill each other a lot less.

I took a trip in 2004, a year after the war started in Iraq. I played music on the streets of Baghdad for Iraqi civilians. I'd also play for U.S. soldiers at night when they were off duty in the bars. Then I would talk to people, and I would film them and ask them about their life and the conflict.

My parents said sticks and stones will break your bones but names will never hurt you. But I always felt a sense of exhilaration after a fight; it was the names that really hurt me.

'Star Wars' is mythology. It's like Greek mythology or Shakespeare. It's the story of good versus evil over a very long span of time. The storytelling is universal and timeless.

I have a desire that I want to make people feel happy through my music. I'm always trying to find optimistic ways to express myself.

Not all artists have a responsibility to be socially or politically aware, but they do have a responsibility to make great art. They have to find some truth and put that in their music.

I came up playing in both punk rock bands and hip-hop bands, and I found a more universal way of reaching people, especially with music that has a message to it.

All the freaky people make the beauty of the world.

Our country was founded on immigration. We are all occupying Native American land here. At what point do we say 'It's our land, and nobody else can come here.'

All my songs are different, but from the overall experience, I want people to sense that they can overcome and move through difficult times and find strength in my music. Maybe it's a song that makes them cry and move through something else.

Everyone deserves music.

I'm always trying to find optimistic ways to express myself.

I eat bags and bags of cashews. I've got them in the kitchen, and about ten feet away I've got another bowl on the kitchen table. In my backpack, I've always got a bag of cashews. I started eating them in the airports because that's the one food that you can find in every airport that's actually nutritious.

The way the music comes to you starts to affect how you listen to music. When you're a kid, it's 'Does it rock? Does it make me feel good? Does it make me tap my feet? Does it make me go to sleep?'

There are so many things to be worried about, and I wanted to make a record that people could put on, and it would lift them up the way the sun did for me each day.

My greatest sense of accomplishment has come from having two amazing sons, but it's also a paradox in that the times when I felt like the biggest failure have been times when I felt like, as a parent, I wasn't making the right decisions or succeeding in the way that I should.

Rap has so many possibilities that need to be explored. There are different factions of rap, but some are in a rut. Rap doesn't have to be about boosting egos and grabbing your crotch and dissing women. There's a way to make political and social issues interesting and entertaining to the young rap audience.
