He let out a yell of joy. They danced round the room. Pressure of population was such that reproduction had to be strict, controlled. Childbirth required government permission. For this moment, they had waited four years. Incoherently they cried their delight.

To qualify as a Seeker, it was necessary to show a high serendipity factor. In my experimental behaviour pool as a child, I had exhibited such a factor, and had been selected for special training forthwith. I had taken additional courses in Philosophical, Alpha-humerals, Incidental Tetrachotomy, Apunctual Synchronicity, Homoontogenesis, and other subjects, ultimately qualifying as a Prime Esemplastic Seeker.

That first novel of mine, Non-Stop, is directly attributable to Heinlein. His "Common Sense" seemed to me such a good story, but bereft of any human feelings. I thought long about that story, and then I thought how wonderful it would be to write about a spaceship in which people have been imprisoned for generations and to put in something of the human feeling. So that novel is directly attributable to Heinlein. I thought, in my youthful arrogance, that I could do it better — I didn't! I thought I could do it differently, and I think I did do it differently. And I suppose that on the whole, I've concentrated on doing things differently ever since.
