While I agree, I know it can be hard to start writing as well, because you are so worried about the quality. One of my professors from college brought up a great point that "No one will read your shitty first draft except you."

I find that phrase very helpful, because usually when I write, the first draft is always a giant mess. But you're able to craft it and edit it the best way that you can. So you can push out what you think is good work, and continue to improve as you write more.
