As a writer, it’s important to remember that only a tiny percentage of people read, far fewer read full articles instead of just headlines, fewer still read books, and — even if it’s a massive hit — only a minuscule fraction of those rarified few will read your book.
Knowing that you will never reach everyone frees you to write for a particular someone. You can tell a singular story just for people like them, a story that speaks to who they are and who they are becoming, a story they won’t be able to put down or forget.
The right book at the right time can make a lasting impact on the life of the right person, and people who read books exercise outsize influence on the world. So while writing books will never earn you a mass audience, it may very well be the lever you need to make the change you seek to make.
