When people say "writing," what they really mean is "re-writing." Nothing you've ever read has been a first draft. Every first draft is shitty. Just get the words out, you'll be getting rid of most of them anyway, but you have to get them out of your head.
Writing is 80/20 skill/talent. Talent you can't do anything about. Good news for you, because the majority of writers became good by just putting the hours in. It's like learning guitar or becoming good at golf or picking up salsa dancing: practice + time = skill.
If you haven't read Bird by Bird yet, go read it twice.
Keep a vaguely detailed journal of what you did that day. Examples: "Went to class, prof wore that same stained sweater vest today," "Coffee with Julie, talked about the fight she and Brent had about coasters," etc. General life stuff you wouldn't think to write in a journal (if you think the goal of that journal is to document EVERYTHING are the little bits in fiction that make it feel real - go back and read these little quips when you're stuck. They'll help you find your voice again). You can write a page and a half about the color of the leaves on the day you first saw the girl you're going to marry, but the more you can make the reader create the image in their head instead of force-feeding it to them, the more it will resonate with them. This is basically show-don't-tell, or Unpacking.

This is a wonderful idea! Have you ever read Lynda Barry's What It Is?
