Sometimes I am happy and sometimes not. I am, after all, a human being, you know. And I am glad that we are sometimes happy and sometimes not. You get your wisdom working by having different emotions.

Marriage is a difficult project. When seven years have passed and all your body's cells have been replaced, you're meant to experience that seven-year itch.

Remember, each one of us has the power to change the world. Just start thinking peace, and the message will spread quicker than you think.

Events are the best teacher for us. You try to learn from people, there is always some bend to it.

Smile in the mirror. Do that every morning and you'll start to see a big difference in your life.

I think that there is a sort of spiritual power that is translating into our bodies as we perform. Performers give, and giving is so important. It can heal. That is my experience, anyway.

Nothing is written in stone. So don't prepare yourself for a long and lucrative career. You might die tomorrow. Your gold holdings might become dust. Just make the music you want to make now and enjoy it.

I relate to happiness as an ecstatic moment - something you don't create, you encounter.

I think there is a big difference between the music business and music. And my relationship is to music, not music business. I think the business will keep changing, but music won't. Music will be there.

This society is driven by neurotic speed and force accelerated by greed and frustration of not being able to live up to the image of men and woman we have created for ourselves; the image has nothing to do with the reality of people.

I just want to be healthy and stay alive and keep my family going and everything and keep my friends going and try to do something so that this world will be peaceful. That is the most ambitious and the most difficult thing, but I'm there trying to do it.

Art is like breathing for me. If I don't do it, I start to choke.

Being alone is very difficult.

The human race is a very, very magical race. We have a magic power of witches and wizards. We're here on this earth to unravel the mystery of this planet. The planet is asking for it.

I'm very thankful that I can make people happy just by signing my name.

When I turned 60, it didn't bother me at all.

After my husband John Lennon passed away, I tried to smile for my health.

Marriage is a gamble, let's be honest.

There's a long life ahead of you and it's going to be beautiful, as long as you keep loving and hugging each other.

People make music to get a reaction. Music is communication.

Art is my life and my life is art.

Society tells you that when you're old you have to retire. You have to defy that.

Nobody's life is a bed of roses. We all have crosses to bear, and we all just do our best. I would never claim to have the worst situation. There are many widows, and many people dying of AIDS, many people killed in Lebanon, people starving all over the planet. So we have to count our lucky stars.

Every drop in the ocean counts.

The computer is my favourite invention. I feel lucky to be part of the global village. I don't mean to brag, but I'm so fast with technology. People think it all seems too much, but we'll get used to it. I'm sure it all seemed too much when we were learning to walk.

I see so many activists... who are artists because they feel that they have the power of communication.

You change the world by being yourself.

Experiencing sadness and anger can make you feel more creative, and by being creative, you can get beyond your pain or negativity.

A dream you dream alone is only a dream. A dream you dream together is reality.

Healing yourself is connected with healing others.

One day, the dance charts will be the biggest chart in the music world. Because we all need to dance. This planet will be a fun planet when the judges in court will end the day with a dance!

In the '60s we fought for peace, when the Vietnam war was on. We were against the cops and against the politicians, and there was a lot of waving banners and all that. And I think in a way, just as they were enjoying that machoism of war, we were enjoying the machismo of being anti-war, you know?

I'm free from holding personal anger because I can express what I want through my music.

Healing yourself is connected with healing others.

Controversy is part of the nature of art and creativity.

Distance doesn't exist, in fact, and neither does time. Vibrations from love or music can be felt everywhere, at all times.

The war industry people are very together; they know exactly what they want; they don't even have to talk to each other. The peace industry people are just intellectuals who are very critical of each other... Unless the peace industry is powerful, we're always going to have war. It is as simple as that.

My husband John Lennon was a very special man. A man of humble origin, he brought light and hope to the whole world with his words and music.

But only art and music have the power to bring peace.

When I'm putting some communication out on Twitter or Facebook or Instagram, I think that it's helping me, my brain, you know, because it's always somehow stimulated by people who are sending things to me. And it works both ways. It's great. My brain is very happy about it.

When you go through a negative situation, don't think about it. Make it positive.
