Seonusan: Take 2

I've got a little over two weeks to train before heading back down to Seonusan and see if I can pull through the crux of Zoo and to the finish.  Mind you, I've never climbed a 5.12 anywhere, even in the gym.  Gym climbing being of course much easier since the holds are marked and you don't waste your time searching for good and and feet placement.  

A few things are on my mind right now.  I'm pretty sure my endurance is much better than it was last time I was there, but I'm not sure I've gotten any stronger.  The crux is a burly move and/or I haven't figured out a way to do it much better.  By late September the temperature should be more comfortable so I'm hoping for a less greasy feel.  This hasn't been an issue until just recently: Can I maintain a training schedule, get enough sleep, stop going out until the wee hours of the morning?  This sucks to admit, but I'm shaky on all three right now.  I only climbed once last week and yesterday's bouldering session wasn't much to talk about.  I've been tired since coming back from vacation (and there are other factors in this) and just based on last weekend and plans coming together for this weekend, can I stay away from Hongdae?  What happened to my near OCD with cllimbing?
