The beautiful part about writing is that you don't have to get it right the first time, unlike, say a brain surgeon.~ Robert Cormier
Recently another writer, Michele Corsanti posted this on her Almond Tree FB page and it spoke to me. The quote is not advice but more of an affirmation to keep on writing.
My advice is to keep on writing, read and re-read your work again. Get a great editor and remember, most importantly remember, that not everyone is going to like what you write. Do not let a bad review deter you from writing.
