Don’t quit.

You’ll find more than enough reasons to give up. Determine to write no matter what.

Study, research, grow, develop a thick skin, work hard, accept editing and input—painful as they can be, and learn to become an aggressive, even ferocious self-editor

Get your seat in the chair every day and get words on the page. They won’t all be perfect, but writing is the only way to get better at it.
