Rejection is always very hard to take. If you receive feedback at the same time, that's great. Otherwise it's hard to know why the story was rejected - useless story or blind editor? I thought this was a good analysis of why stories get rejected.
The reason i mention this is - yes, rejected again (but speedily). In one way, I'm not surprised - I like the story but maybe it needs more polish. Perhaps the main character isn't likable (or dislikable) enough. I will re-read and amend before I send out again.
A couple of weeks ago my % acceptance in Duotrope was 75% - now it's 37.5%!!
Perseverance is key to success, I think.
