Writing Weakness!

I think that the rule from Kurt Vonnegut that will be the toughest for me to follow will be "sound like yourself". I get very caught up in attempting to make sure that all of my grammar is accurate and it makes me second guess sounding like myself. I typically end up writing and rewriting my final draft several times because I feel that it sounds too much like the way I speak on a regular basis, which isn't always correct grammar or speech. I am excited to learn a little more about sounding natural and making things flow better with out changing the fact that it is actually me writing a piece.
