Stuck, again

I'm in the middle of post-holiday syndrome. Yep, it's the work-blue syndrome. It means there are a lot of things to do but I chose to do something else that has no relation to it. Well well..bad habit..it comes again. My brain seems to refuse to work, for whatever reason I dont know. It just shut the door to the cortex close. I couldnt command it to open and do a simple analysis. I feel so stupid these days. I stared at the laptop screen and found nothing. Not any ideas spark out of my mind. They just conspired against me I guessss....*sigh*. Do I need more holiday? That's just too much, I've just had 2 weeks and want more? Is it what they called 'deterioration'? Hope not :(
