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).

Writing is the act of creation. Put words on page. Words to sentences, sentences to paragraphs, paragraphs to 7-book epic fantasy cycles with books so heavy you could choke a hippo. But don't give writing too much power, either. A wizard controls his magic; it doesn't control him. Push aside lofty notions and embrace the workmanlike aesthetic. Hammers above magic wands; nails above eye-of-newt. The magic will return when you're done. The magic is what you did, not what you're doing.

In my mind, only one inviolable precept exists in terms of being a successful writer: you have to write. The unspoken sub-laws of that one precept are: to write, you must start writing and then finish writing. And then, most likely, start writing all over again because this writing "thing" is one long and endless ride on a really weird (but pretty awesome) carousel. Cue the calliope music.

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.

When in doubt, the rule of threes is a rule that plays well with all of storytelling. When describing a thing? No more than three details. A character's arc? Three beats. A story? Three acts. An act? Three sequences. A plot point culminating in a mystery of a twist? At least three mentions throughout the tale. This is an old rule, and a good one. It's not universal - but it's a good place to start.

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.

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.
