1. You must write.
2. You must finish what you write.
3. You must refrain from rewriting, except to editorial order.
4. You must put the work on the market.
5. You must keep the work on the market until it is sold.
That’s from an essay Robert Heinlein wrote in 1947. All I can add is: Amen. Also, try to write good stories. Stories that aren’t going to make the ghost of my deceased grandmother rise up from her grave and haunt you until you run screaming off a cliff.
Or something like that.
