I’ve always wondered about the “write what you know; write what you like” rule. By and large, I agree with it. You learn your craft by staying close to home. There’s less to think about, less to worry about, less to make up. It’s a forgiving environment.
But after a while, dogma can take over. After all, I like chicken wings. I know chicken wings. I eat all kinds of chicken wings. But that would be pretty boring to read a whole book of poems on chicken wings. Might be fun to write though.
