John Green once said, "Nerds like us are allowed to be unironically enthusiastic about stuff. Nerds are allowed to love stuff-like, jump-up-and-down-in-your-chair-can't-control-yourself love it." It's a great quote. And it's not just true for nerds. The same can be said of writers.
Writers have to love stuff. You wouldn't spend hours, days, weeks on something you didn't love. You wouldn't give up precious family time or turn down social invitations to sit alone at a desk if your heart wasn't in the work. You couldn't. You couldn't deal with the frustration, the setbacks, the rejections if you didn't absolutely love your story, your concept, your characters.
Personally, the act of writing makes me happy. It's like someone takes a pitcher full of joy and pours the whole thing into my chest. I feel light with excitement. While everyone is different, I'm sure other writers experience similar emotions.
However, while I love what I do, what I create, sometimes I forget all of that. I go long periods without writing. I drift. And I know I'm not the only one. I know someone else is probably drifting right now.
So, here's a reminder, fellow writer. You love writing. I know you do. It's in your title. Writing is loving. And love affairs require two participants. There's a story out there, waiting for you. Go to it. Get reacquainted.
