Talent is just the necessary-but-not-sufficient condition for a career as a writer. … Have talent, then learn your job. That starts with the mechanics of writing — how to create a character, how to define a milieu, how to distinguish voice, how to plot, pacing, all that stuff. You know, the writerly stuff.
It also means understanding the market, and understanding the business. … Go to your local book store. Stare at the shelf you want to be on. Read and stare and read and stare until you understand what you’re looking at. That’s your market.
You know why I list my occupation as “writer” and not “author?” Author is a title. Writing is a job. Don’t be something, do something. Put your fingers on the keys and make words appear on the screen.
Have some talent, learn your job, understand the market, and do the work. And then you’re very likely to make a living. And if you also get really lucky you get the castle in Scotland and you can hire Mr. Bates to dress you every morning while Mrs. Patmore makes your pancakes.
