If you claim that you are a writer, than you should be writing.
You don't have to be published. You don't have to be on the New York Times bestseller list.
You just have to be BOCHOK (Butt On Chair, Hands on Keyboard)
I have an acquaintence (one of the very few people in my life I have had a genuine falling out with) who claims to be this writer who is going to shake the world. I truly wish him the best, but he has not even attempted to write for five years even though he still brags about his ultimate goals.
If you want to be a writer, that's awesome. Remember. BOCHOK.
