Revision Day 2

It is hot still. I am sitting here eating corn chips and drinking lukewarm coffee that I am unwilling to reheat, mainly because I had to spray down the whole stupid kitchen thanks to all the goddamn ants that decided this heatwave would be a great time to repopulate and come hang out on the floors and countertops. I had to block off the kitchen because of this, which means that the dog is panting worriedly at my feet because she is a border collie and panting worriedly is pretty much her hobby.

Ugh. Too many corn chips. Whose idea was that?

Anyway, this is officially day two of revisions, and I've...well, I've not really done anything yet. Day one was a fairly good success. I got through the first five chapters, and that five week wait really did help. I tend to be obsessively critical of my work, and when Stephen King's book told me (more accurate than the phrase I used last time) that I should wait and will then find myself being less critical, I thought the book was probably lying to me and spreading rumors. So I decided to start revision immediately.

This happened. I started obsessively rewriting every single sentence, twisting the words around and adding new words and attempting to be creatively alliterative and blahblahblahblah.

So I put it away.

This is what my revision scheme looks like after waiting:

Much less critical! There are still quite a few notes and words scribbled out and things underlined and what have you, all done in the lovely green of the Sonic Screwdriver Pen gifted to me by the illustrious Ms. Ashke, but it doesn't seem as awful as it did when I tried revision directly following the printing. However, I think that the parts I'm heading into now may contain some serious problems in terms of silly little things like logic and continuity, so I'm balking a bit. 

Plus it doesn't help that I've been continuously distracted by my phone. Last night it was lying to me and St. John (Or is it St. Matthew?) about whether or not Jupiter was where we thought it was, this morning it was apparently receiving text messages from Nora Hawthorne (the love child between Nora Roberts and Nathaniel)'s sink. The inimitable Ms. Ashke's pocket dialed me next, and now one confused person is sending me pictures of a menu where everything is named after a work of literature. I told her to get the Edgar Allan Potatoes. 

I'll try and do something, though, because Hemingway will be here soon, and we're off to see my famous actress friend's play tonight. However, I have a question:

How much backstory is too much backstory? My main character, Andy, has a past that is not fully discussed in the book I'm revising now. However, her past is completely the focus of the second story (if St. Luke and Woolf don't tell me to go hang it all and never write on this again), so how much do you think would be apt for the first in terms of teasers or whatever the hell. I don't really know what I'm asking. Just... backstory! What do you think! Thanks!
