Hi all

well after finishing my rough draft i discovered i need to do a complete rewrite, how many time have you done a rewrite?
when do you fill your story is good enough to send to an editor? when you and your Friends like it, or would you give your book to a stranger for a critic?

I feel my cliche in every chapter are good and plot and flow work nice together, and the climax is riveting. but every time i read my work I find many things i could make better but every time i change more than i should...
When do you know good is good enough?
thx for any input.
