Like that one guy said: Good writers borrow, great writers steal. Welcome to the place where all things have been lifted, looted, and otherwise pilfered...Remember, possession is 9/10s of the law.
Best advice: Find a GOOD critique group. I got lucky and found a great one.Worst advice: Just pitch the unfinished manuscript for practice. Unfortunately, that one came from my own little brain.
Fellow thieves! Please feel free to let me know what you've taken from this post - or share pertinent information that you don't mind me stealing.
