To go to prison because of your convictions and be prepared to suffer for what you believe in, is something worthwhile. It is an achievement for a man to do his duty on earth irrespective of the consequences.

The only real mistake is the one which we learn nothing.

I don't like to be labeled, to be anything. I've made the mistake before myself of labeling my music, but it's counter-productive.

Some mistakes will be made along the way. That's good. Because some decisions are being made along the way. We'll find the mistakes. We'll fix them.

The work of Dr. Salk is in the highest tradition of selfless and dedicated medical research. He has provided a means for the control of a dread disease... by helping scientists in other countries with technical information; by offering to them the strains of seed virus... by welcoming them to his laboratory that they may gain a fuller knowledge... his achievement, a credit to our entire scientific community, does honor to all the people of the United States.

The biggest mistake Yoko and I made... was allowing ourselves to become influenced by the male-macho 'serious revolutionaries,' and their insane ideas about killing people to save them from capitalism and/or communism (depending on your point of view). We should have stuck to our own way of working for peace: bed-ins, billboards, etc.
