I only write when I'm sad. Notice how I only have 1 entry in 2013 but have several for October 2014. I'm not a great writer. I even think it's pretentious to call myself a writer. But the ones I manage to publish and post turn out okay, and I do get asked why I don't write that often.
I only write when I'm sad. And sadness is a feeling I've been trying to escape my whole life.
