We feel that even if all possible scientific questions be answered, the problems of life have still not been touched at all. Of course there is then no question left, and just this is the answer. (Tractatus)
I think this is correct, although the way he put it sounds awfully mysterious. It simply means that "the problems of life" are solved by making choices rather than discoveries. The meaning of life is about how to change things, rather than merely about figuring out how things already are. The more controversial implication of what Wittgenstein is saying is that there can be no recipe for creativity.
