Razor - a good tip for you when editing. Give it a few days and edit in spurts.
When I edit I do so in short blasts. I put down the piece than go back, re-edit what I edtited and then edit a new part. Then I go back later re-edit the newly edited part and then edit another new part. My pieces get several edits that way and I actually am more meticulous if it is something to post in the main story library. Here it is not quite so important to have it perfect - you are learning and getting torn apart - nit picked til you can't see straight.
But do take your time. Hurrying will fuck you without giving you a kiss.
