“Use what talents you possess, the woods will be very silent if no birds sang there except those that sang best.”
- Henry van Dyke

Don't not write just because you don't think your writing is worth reading. Everyone has to start somewhere, and if you never start, you'll never get better. Everyone also has room to improve, always, especially because writing is an art - there's no "right" or "wrong" way to write. You just have to do it. A good writer isn't one that writes a perfec first draft (and trust me, first drafts are never perfect) a good writer is one that knows how to edit and rewriter that first draft to make it good. But what you need before you can edit anything is a manuscript to edit, which is what NaNo's for! So kill your inner editor for these next three weeks and write that first draft so you can go back and edit in December, or January, or whenever you have time, because as long as you have it, this first draft isn't going anywhere.
