revision strategy or superstition?

I rarely do simultaneous submissions. Nothing moral about it, I just can’t keep track. I do send out to a second place if the first place is taking for-fricking-ever to respond, since I can’t recall having something out there for 2/3rds of a year producing an acceptance. Regardless, if I haven’t gotten and answer or I’ve been rejected, I always make some sort of change to the piece before I send it out again. Sometimes this is in response to an editor’s criticism, and the change is substantial. But mostly it’s a little tweak, unnoticeable to anyone but me. For example, in the story I have coming out next, I removed the word “dewy.”
