WIP Challenge Check-in, Day 21 -- Thursday

[linaewen]

Very sorry to miss yesterday -- I had to go out early, and then totally forgot I hadn't posted anything for Wednesday!  So anyway, what kind of a writing day has it been today -- or yesterday/the day before, if today hasn't gotten going yet?

•     I thought about my fic once or twice
•     I wrote
•     I did some planning and/or research
•     I edited
•     I've sent my fic off to my beta
•     I posted today!
•     I'm taking a break
•     I did something else that I'll talk about in a comment

Discussion:  Sometimes errors occur as we write that we miss until much later, and then it's a huge burden to try to go back and repair the damage.  Does this happen to you?  How do you deal with it, and how do you prevent it?
