Your job is to do the work, put it out there and let the world decide.
Now, I know that sounds scary. But let’s be dead clear about something: You’re not John Steinbeck (and neither was he, at the start). You have to get there first. And the only way to do that is through practice and criticism. But the only way to get practice and criticism is to make and share your work.
This isn’t just about writing. It’s about anything meaningful you do. Singing, painting, entrepreneurship, giving financial advice, museum curating, boat building, skiing, whatever. Whatever it is, your job is to do the work, to become the best you can be.
