Literature deserves its prestige for one reason above all others - because it's a tool to help us live and die with a little bit more wisdom, goodness, and sanity.
In journalism, if there's a hole in your story you figure out a way around it because you've got a 4 p.m. deadline. It's a neat skill to have but it's deadly for literature. In literature, you need to stare at that hole, not ignore it. You need to figure it out.
With no other privilege than that of sympathy and sincere good wishes, I would address an affectionate exhortation to the youthful literati, grounded on my own experience. It will be but short; for the beginning, middle, and end converge to one charge: NEVER PURSUE LITERATURE AS A TRADE.
