The interview I mentioned earlier is now up on the blog Grinding to Valhalla.
Relevant quote:
Would you have any words of advice for the would-be-writers out there?
Two things. First, only pursue this if what you love, and what you want out of it, is the writing. It takes years to build a career at this, and a love of writing is the only thing you have to get though those years of effort. Second, if you pursue this, you must persist. You must start writing. You must finish what you start. You must submit what you have finished. And you must then start writing something else. Otherwise decent writers remain unpublished because they become hung up somewhere on the process, they never finish, they revise endlessly, they don’t submit their work to markets, or they don’t start a new project while they’re peddling the old project.
