There is only one way you will ever be able to write for a living: You must write words that people will pay money to read. If you do that, you’ll make a living as a writer. If you don’t, you won’t—simple as that. The money you make as a writer represents more than just the ability to pay the mortgage and buy groceries. It is the writer’s strongest and finest affirmation. It is tangible proof that someone thinks your words are worth purchasing and paying attention to.
There’s nothing crass or ignoble about trading your writing for money. Your words are your stock in trade. Doctors sell their medical knowledge for money, lawyers sell their legal knowledge for money, and you sell words. If they are good words—well-chosen, skillfully crafted, filled with ideas and energy—the world will buy them. You prove your own craftsmanship by writing saleable words. It’s a great feeling to receive a check for a publisher’s advance; but it’s an even greater feeling to receive a royalty check, because that means that it’s not just the publisher who likes your words; the public is willing to pay money to read them.
It is that feeling that enables you to say, boldly and unabashedly, “I am a writer.”
