I realized that if my thoughts immediately affect my body, I should be careful about what I think. Now if I get angry, I ask myself why I feel that way. If I can find the source of my anger, I can turn that negative energy into something positive.

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

Is truth always positive? Of course. Once the truth comes out, you know, it's all right. We're scared that if the truth comes out that it's not all right. It's the other way around.

Great Art is Great because it inspired you greatly. If it didn't, no matter what the critics, the museums and the galleries say, it's not great art for you.

My beauty secret is... nothing! I don't drink too much water. I don't eat very well. Sometimes I cheat and grab some chocolate. The best thing is to eat what you want, but not very much.

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

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

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.

Many incredible artists die before they were famous.

People think that their world will get smaller as they get older. My experience is just the opposite. Your senses become more acute. You start to blossom.

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

What the Beatles did was something incredible, it was more than what a band could do. We have to give them respect.

I respect Lady Gaga very much.

The regret of my life is that I have not said 'I love you' often enough.

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.

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.

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

I was being hated for about 40 or 50 years by the whole world, but it did not destroy me, and it did not ruin my health. And the reason is because I just did not answer them. I had my own life.

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 did not break up the Beatles. You can't have it both ways. If you're going to blame me for breaking the Beatles up, you should be thankful that I made them into myth rather than a crumbling group.

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

I've always said that I use my voice as an instrument. It was something I created myself, and I said, 'Have voice, will travel.'

I travel a lot, so when I arrive in a city, I like to go to good local bookshops and make a selection based on how I'm feeling and what I'm thinking. The book I pick usually seems to have a definite karmic connection!

I trust myself. You need that to survive.

Marriage is a gamble, let's be honest.

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.

We live too long for one marriage.

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.

The nice thing about the gallery shows is that without having to pay any money you can just go and see it.

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

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

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?

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.

Words are power. And a book is full of words. Be careful what power you get from it. But know that you do.

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.

To have a relationship that is pure and passionate and beautiful - I think people are scared of having that now. Especially guys.

The universe, when you leave it alone, is going to be beautiful.

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

Losing my daughter was a very serious pain. There was always some empty space in my heart.

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

The sky is always there for me, while my life has been going through many, many changes. When I look up the sky, it gives me a nice feeling, like looking at an old friend.
