Shut up and write anyway. Don't use anything as an excuse.
I am free to write the worst junk in the world.
Writing can teach us the dignity of speaking the truth.
The things that make you a functional citizen in society - manners, discretion, cordiality - don't necessarily make you a good writer. Writing needs raw truth, wants your suffering and darkness on the table, revels in a cutting mind that takes no prisoners.
I consider writing a legitimate Zen practice.
That's very nice if they want to publish you, but don't pay too much attention to it. It will toss you away. Just continue to write.
