The trick is to pick several up at the same time and smush them together until some of them stick to each other—creating something new and interesting.
But, lest anyone think that the art of writing speculative fiction is no more than being able to create interesting new hybrid constellations of ideas, he concludes with the warning:
Ideas, hah. The real challenge in this line of work is being able to weed the productive ones from the chaff, to decide which you’re going to spend the next six to nine months turning into something that people will pay for.
