Writing relies on very few things, my friend. All you need to write is your brain, a way to convey the story into existence (pen, computer, whatever), and a place in which to do it (office, kitchen table, lunar brothel).

You can feel good about failure. Failure means you did something. You finished the story even if it wasn't what you'd hoped. Failure means you're learning. Growing. Doing.

Story matters. Writing is important. Stories make the world go around. Many things begin as words on a page. It matters to the world. And it matters to you. Don't let anyone rob you of that. Don't rob yourself of it, either. Don't diminish. Don't dismiss. Embrace. Create. Accelerate.

Enter the story as late as you can.

Write til your fingers bleed.

Speed is not an indicator of quality in terms of fiction. That's true of one's relative slowness or swiftness - taking 10 years to write a book or taking 10 days to write a book (or a comic or a film or an angry postcard) guarantees nothing in terms of how good or how bad that story is.
