Don't be a competent clone: David Mitchell's writing advice

In a recent interview, Mitchell gave some awesome advice for young writers. He wanted to be a writer in order to "do to other people what [his] favorite authors had done to me."

A few parts really stood out for me:

"Send the thing out and forget it. Quickly get to work on the next thing. Don’t sit by the phone or watch your email. Don’t hope. You’ve done a big thing by finishing something. Spend all the energy on possible despair. Avert that possible despair. Transfer the despair to the next manuscript. Right away, like the next day."
If you don’t want to write a realist novel, that’s not who or what you are. Work out the kind of novel you want to write, that you’re best suited for and do that one instead. It’s likelier to be more interesting. It might be awful but it won’t be a clone. Better to be brilliantly bad with your first novel than competently clone-like.
Things that are your obstacles often turn out not to be. Things you think are stopping you from writing, these distractions, can feed into your work in positive ways. You just may not know it yet. Things you don’t want to discuss—your scars, your shadows, your psychological baggage from childhood. It’s useful. It’s therapeutic to deploy them. You kind of win by using them. You can give them a right to exist but actually give them a job to do as an informant about reality, about language, about the human heart.
