Life is about choices. One choice will get you closer to being the one you imagined yourself. The other choice will get you closer to the person you should be.
You don't write and you don't write and you don't write because you're content, and the vodka is nearby, or a significant other is talking to you online.
But then you are alone one night and alone and alone and it's the same night still, and what can you do but write?
