For me, no word comes without prior thought. No sentence is generated without effort. No formulation is made automatically. I am faced continually with a mystery that other people have no conception of, the mystery of the generation of speech. There is no command situation, it goes back and back and back. Where the self lies at the heart of the utterance, the speaker generating the word, is always clouded. This is true for everyone, but for most people this is not something to think about. The generation of words is automatic. For me, that automatic link is broken. Word generation involves strain, guesswork, difficulty, imprecision.

More than anything else, I had to combat the barriers, and we tore down those barriers. I just had to set a sail against the wind, those strong winds, to end segregation and racial discrimination, but somehow, in some way, I didn’t let those barriers keep me down.

At Cornell, I’d work on preparing my courses, and I’d go over to the library a lot and read through the Arabian Nights and ogle the girls that would go by.  But when it came time to do some research, I couldn’t get to work.  I was a little tired; I was not interested; I couldn’t do research!  This went on for what I felt was a few years, but when I go back and calculate the timing, it couldn’t have been that long.  Perhaps nowadays I wouldn’t think it was such a long time, but then, it seemed to go on for a very long time.  I simply couldn’t get started on any problem: I remember writing one or two sentences about some problem in gamma rays and then I couldn’t go any further.  I was convinced that from the war and everything (the death of my wife) I had simply burned myself out.

I would say there are many challenges, and that's kind of what's hard about it. And my particular thesis, since leaving Google and doing my own company, is that building a quantum computer is a little bit harder than the scientists think about because of the system engineering. Building a powerful computer is hard. So what we're particularly working on is the manufacturing of qubits and doing that much better than what people are doing right now. I really enjoyed being in academia, and even at Google working on that. But I really enjoy right now trying to think very practically about what we have to do to get this to work. And what kind of people we have to collaborate with in order to put all the pieces together and build a quantum computer in a cost effective, economic way that makes business sense.

Oh, absolutely. I think most overachievers are driven, not so much by the pursuit of success, but by the fear of failure. Unless failure gets very close and very nearby that fear doesn’t reach profound levels, but it drives us. It drives me to work very hard.
