I think first one has to learn the field thoroughly enough so that you can see the things that are promising. That means you work with somebody else who’s an expert, try to learn from them, you take classes, you learn everything you can. At some point, you’ve learned enough that then you can perhaps be clever and wise about what next to do. And once you start doing that then, for me at least, everything sort of grows out of the things before. You take whatever experience you have, and that’s true of course of all of life, you take whatever experience you have, and you project it forward, and what new things you might do with that expertise or knowledge or experience and judgment. I would say, in a sense, almost everything I have done, while it may seem very different scientifically, it really is a continuous stream of things, branching off here and there, you see, in various directions, but still very closely connected.
