Often one of the biggest excuses to not write you’ll hear from an aspiring writer is that they’re not “in the mood” (or perhaps that they are “waiting for inspiration”). On the one hand, it’s important to realize that writing, just like all other forms of art, is work. You have to sit down and do it on a regular basis, no matter what, regardless of how you feel about it. If you don’t, you never get better. On the other hand, there’s nothing to say that you have to slog through the writing in the most disagreeable way possible. It’s a difficult task, you might as well try to find ways to do it that don’t fight with human nature.
