We work with young people, from the ages of 11 to 17. Our main program is the Pathways to Freedom. And we’ll be going from Memphis, Tennessee through ten other states, and Washington, DC, and to Canada. It began July 13th and ends August 8th. We hope to take as many young people and their chaperons as possible throughout these areas, and stop and have workshops and programs. They’ll be traveling in buses, and we hope that will inspire and give them a sense of history and also to encourage them to be concerned about their self and history and motivated to reach their highest potential.

Painting is complete as a distraction. I know of nothing which, without exhausting the body, more entirely absorbs the mind. Whatever the worries of the hour or the threats of the future, once the picture has begun to flow along, there is no room for them in the mental screen. They pass out into shadow and darkness. All one's mental light, such as it is, becomes concentrated on the task. Time stands respectfully aside, and it is only after many hesitations that luncheon knocks gruffly at the door.

The proudest achievement of my life at that time was that software. Wonderfully organized, extensible, and efficient: the culmination of everything I’d learned about programming in ten years. After a successful relaunch and Christmas rush, I was looking at my plan for 2008 and beyond. All my plans needed a huge effort for little reward, but were required for future growth. I had broken it into about 20 projects, each taking 2 to 12 weeks. But I wasn’t excited about any of them.

There was no importance to what I was doing, but ultimately there was.  The diagrams and the whole business that I got the Nobel Prize for came from that piddling around with the wobbling plate.

It is necessary, I believe, to accept this idea, not only for science, but also for other things; it is of great value to acknowledge ignorance.  It is a fact that when we make decisions in our life we don't necessarily know that we are making them correctly; we only think that we are doing the best we can – and that is what we should do.

So I wish to you—I have no more time, so I have just one wish for you—the good luck to be somewhere where you are free to maintain the kind of integrity I have described, and where you do not feel forced by a need to maintain your position in the organization, or financial support, or so on, to lose your integrity. May you have that freedom. May I also give you one last bit of advice: Never say that you'll give a talk unless you know clearly what you're going to talk about and more or less what you're going to say.

I don’t believe I can really do without teaching.  The reason is, I have to have something so that when I don’t have any ideas and I’m not getting anywhere I can say to myself, “At least I’m living; at least I’m doing something; I’m making some contribution”—it’s just psychological.

Then I had another thought: Physics disgusts me a little bit now, but I used to enjoy doing physics.  Why did I enjoy it?  I used to play with it.  I used to do whatever I felt like doing—it didn’t have to do with whether it was important for the development of nuclear physics, but whether it was interesting and amusing for me to play with.

The first principle is that you must not fool yourself—and you are the easiest person to fool. So you have to be very careful about that. After you've not fooled yourself, it's easy not to fool other scientists. You just have to be honest in a conventional way after that.
