I think, for the most part, what most writers come up with is based upon the mundane, it is their perspective upon it, wherein lies the genius.
Some have it and it is truly a gift. Others will still manage, even at three pages a day, to only come up with the mundane. The ability to paint vivd images, that make connections for others, with few words, is one of the few things I truly envy. I don't think I will ever manage to do that, even at double the output and time.
