It's very easy to get caught up in the land of comparison.
However, I force myself to take a step back and remember that they were once where I am. It's very rare the person who can just throw words at a page and have them land on the page in pristine perfection.
I remember listening to an interview with Yoyo Ma, and he talked about how people who came to a live performance would never be able to hear what they can on the CD because there aren't retakes, cuts, perfection.
But as writers, we have that opportunity to create perfection. At least, our own version of perfection.
It's important in the meantime to remember that at one point in time, someone out there was pulling their hair out trying to tweak the character, scene, dialogue. And at one point in time, Yoyo Ma made a bow squeak across his strings.
We all have to start somewhere. Just don't let go of the joy.
