Professional writers and artists sometimes forget that they are human beings. In the immense pressure to monetize their work, develop personal commercial brands, and get recognized as professionals (because without such things, capitalist culture regards an artist as a hobbyist at best), they can forget that their art is only one part of who they are. It might be a very large, dominant part, but they exist as multifaceted, complex beings who cannot be wholly defined by what they produce for others to consume.
Forgetting their humanity leads creative people into a lot of pain and self-torment, especially during those inevitable times when they're not producing a lot of work and they feel like they don't matter and might not even really exist.
That's when it's important to remember that it's not how often or how much you produce that makes you real. It's how committed you are inside—knowing that you will return to the work in time and putting your faith in the creative impulse to guide you. Inspiration will return. And so will you.
In the meantime, make the other parts of your life as deep and as excellent as you can, which is a never-ending practice you owe to yourself and to those who have nurtured you along the way, crucial to your wellbeing. You are not a content machine. You are a channel for something greater than your anxious everyday personality. Remembering that, honor who you are.
