What words of wisdom would you give to a new writer?  Perhaps to write every day?  Write what you know?  Try to build a world for your characters?  All these would be appropriate advice. 

Interestingly, in October 1925, a young writer named Ernest Hemingway wrote a letter to a younger Canadian author named Morley Callaghan.
Callaghan was frustrated with his writing life and wrote to his friend: “Have a lot of time and could go a good deal of writing if I knew how I stood.”
Hemingway’s response is included in volume two of The Letters of Ernest Hemingway, out this month. It is terrific advice for writers of any age…
Christ don’t be an ass and say you could go on and write if you know how you stand etc. God knows you’re in the most depressing and discouraging surroundings–but that’s what makes a writer. You have to catch hell. You’ve got to take punishment … Write a lot–but see a lot more. Keep your ears and eyes going and try all the time to get your conversations right.
        Never one to mince words, Hemingway called them as he saw them.  This, of course, was no exception.  The other question then is :  What happened to Morley Callaghan?   He was apparently concerned late in life that people would remember him for one minor achievement: the little Canadian had knocked down the macho Ernest Hemingway in a boxing match refereed by F. Scott Fitzgerald.  Although Callaghan preferred to be known for his novels, it's his short stories that are his lasting legacy. Along with the fact that he knocked down Hemingway in a boxing match refereed by F. Scott Fitzgerald
