Stephen King equates talent to a vein of gold in a mine. One has to do the hard work of digging for the ore, refining, etc. (the nasty work most people don’t want to do). He says if you spend an hour and a half a day writing for ten years, at the end of ten years, you’ll be a pretty good writer. Just as if you spent an hour and a half a day digging, mining, and refining ore, you’d eventually have decent stockpile of gold.
