Nina Holton, whose playfully wild germs of ideas are the genesis of her sculpture, is very firm about the importance of hard work: "Tell anybody you're a sculptor and they'll say, 'Oh, how exciting, how wonderful.' And I tend to say, 'What's so wonderful?' It's like being a mason, or a carpenter, half the time. But they don't wish to hear that because they really only imagine the first part, the exciting part. But, as Khrushchev once said, that doesn't fry pancakes, you see. That germ of an idea does not make a sculpture which stands up. It just sits there. So the next stage is the hard work. Can you really translate it into a piece of sculpture?"

Jacob Rabinow, an electrical engineer, uses an interesting mental technique to slow himself down when work on an invention requires more endurance than intuition: "When I have a job that takes a lot of effort, slowly, I pretend I'm in jail. If I'm in jail, time is of no consequence. In other words, if it takes a week to cut this, it'll take a week. What else have I got to do? I'm going to be here for twenty years. See? This is a kind of mental trick. Otherwise you say, 'My God, it's not working,' and then you make mistakes. My way, you say time is of absolutely no consequence."
