God is a concept by which we measure our pain. - John Lennon

"Life is very short, and there's no time for fussing and fighting my friends"

"You may say I'm a dreamer, but I'm not the only one. I hope someday you'll join us. And the world will live as one."

"When I was 5 years old, my mother always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down ‘happy’. They told me I didn’t understand the assignment, and I told them they didn’t understand life."

"I wasn't saying whatever they're saying I was saying. I'm sorry I said it really. I never meant it to be a lousy anti-religious thing. I apologize if that will make you happy. I still don't know quite what I've done. I've tried to tell you what I did do but if you want me to apologize, if that will make you happy, then OK, I'm sorry."

"Our society is run by insane people for insane objectives"
