This time from Ursula K. Le Guin, an interview at Interview.
If it’s tl;dr here’s my favourite quote:
There’s always room for another story. There’s always room for another tune, right? Nobody can write too many tunes. So if you have stories to tell and can tell them competently, then somebody will want to hear it if you tell it well at all. To believe that there is somebody who wants to hear that story is the kind of confidence a writer has to have when they’re in the period of learning their craft and not selling stuff and not really knowing what they’re doing. It’s like being adolescent for years and years after your adolescence.
And now I’m back to work!
