John D. MacDonald: A Writer’s Writer

“With sufficient funds to cover four months’ living expenses, he set out and wrote at an incredible pace, providing eight hundred thousand words. Writing for a wide variety of magazines, he kept more than thirty stories in the mail constantly, not giving up on a story until it had been rejected by at least ten markets
In the process he accumulated almost a thousand rejection slips after five months of effort. During this period, MacDonald worked fourteen hours a day, seven days a week, literally learning his craft and gaining the experience of a decade as he went along, which was important for a man who made no serious attempt to write until he was thirty.”
– Martin H. Greenberg, in the introduction to Other Times, Other Worlds.
That is how John D. MacDonald, thirty years old, fresh out of the military in 1946 and with one published short story (which he actually sent to his wife in a letter: she submitted it to a magazine) learned the craft of fiction writing.
One of America’s finest writers (note: I didn’t qualify that with the word ‘fiction’) set himself upon a course that no sane person would have undertaken in that situation.
