Write because you want to write, because you need to write, because you are driven to write, because when you don’t write you start feeling squirrelly. Don’t write for fame and adulation–because the chances are, you won’t get it. Go to any bookstore and scan the shelves of published authors for names you never heard of. You are not likely to win a Pulitzer or a Nobel Prize for literature. You aren’t likely to make it on Oprah–especially now that she is bringing her show to a close! Even the non-paying literary journals are very competitive.
Botom Line: putting your work out into the world is likely to result in a lot of rejection. Learn to live with it. And keep writing.
