I was in broadcasting (still am, a bit) and wrote news copy for years. But it wasn’t until I was in my early 50s that I started writing personal essays, memoir, eventually fiction, and then more memoir. I have had six books published, the latest coming out in the spring, by traditional publishers and it’s been and still is a fun ride.
It’s such a cliche, but so true: DO NOT let others tell you you can’t do this. DO NOT let people put you in a box (write this way, do these six steps, etc.). DO NOT let up. Write, Write, Write! And READ. All the time. The words of great authors are the fertilizers for your flowers!
