how to become a novelist

"I'm struck by how, except when you're young, you really need to prioritize in life, figuring out in what order you should divide up your time and energy. If you don't get that sort of system set by a certain age, you'll lack focus and your life will be out of balance. I placed the highest priority on the sort of life that lets me focus on writing, not associating with all the people around me. I felt that the indispensable relationship I should build in my life was not a specific person, but with an unspecified number of readers. As long as I got my day-to-day life set so that each work was an improvement over the last, then many of my readers would welcome whatever life I chose for myself. Shouldn't this be my duty as a novelist, and my top priority?"
