Okay, you’ve dabbled at poetry. You’ve written a short story or two, and then you’ve been fortunate and had a memoir piece published. Now you’re considering a novel. Okay, so what are you: poet? Short story writer? Memoirist? Novelist?
I tried a parse these questions in this post, perhaps successfully. Perhaps not. But every writer needs to know his/her temperament. i.e., one needs to know oneself, the filter through which the words and stories come.
Take the time to do that. It’ll make your writing stronger.
