I have a tip. It works for me, and apparently for Vytanni. I don't know if it works for everyone though.
Think of what your point is. Think of the essence of what you are trying to say is. Then just WRITE! Sometimes, the right words will just flow out into your fingers, and you will finish writing and look at it and think, "Wow! Did I actually write this?!" Especially if you are trying to do a "truth-bomb" type thing, or a redemption or salvation scene, this can work really well. I can't wait to see what you come up with!
