Two Cultures
To use language is to have the capability for music, although the converse is not necessarily true. But writing from both perspectives can result in something richer. If writing prose is being inside all the time, going outside to do something else enriches the inner experience. For many creative people, leaving the workspace and returning to it, somehow re-activates it. Incubation usually doesn't happen while working because you're concentrating on the work. But it can occur in different domains. This is why it's useful to do more than one thing: you can go outside and inside, which allows incubation on two levels, then informing both.
