As a writer you inspire others with your stories. No matter what you write, someone somewhere is going to take something valuable from your words. Think about that.
What you have to say is important. What you do by creating worlds and plots and characters is a service to other people. We all need inspiring, we all need a nudge now and again to think outside the box. As a creative, that’s what you do. That’s your essential contribution, you are possibly shaping the minds of generations to come.
So don’t take your writing lightly. Don’t think it’s not important. People need to know they can take on, fight, and beat the dragons of their world. And yours might be the one voice they listen to, the one voice in its own way and from its unique perspective, that tells them they can.
