The goal for the novice (or even the not so novice) writer is to write better. That doesn’t necessarily mean writing to a grammatical gold standard, or following the rules laid down by the late and the great. It just means finding the words to tell your story in the way you would like it to be told. In your voice.
The thing is, we are all capable of moments of clarity where we say what we intended, in a way that hits home and actually means something. But we are also capable of saying the wrong thing, doubting ourselves, stammering like a loon and then bailing on the big moment we had been building up to. The great thing about writing is we can sift through the first draft and keep the good bits, and keep reworking them until they say what we meant to say.
