Over time, anything will seem like work when it become repetitive. I would've suggested to switch around your work lifestyle, but I'm unsure what kind of implications/consequences that will have. I think once you finally get your mind straightened, you'll be back at having fun with NG.
Also, you really need to get some sleep. That insomnia can really mess with your head when you're trying to do anything.
As far as the air conditioning goes, it sounds like you really are recovering from a slight bout with "weekday blues."
I mean there's people who go through a lot when they go to work. So maybe if you consider yourself lucky in your position, since you seem to be pursuing a dream, you'll begin to appreciate it again.
Working 9 to 5 in hard labor, and then breaking your ankle at work, and having to deal with that, you really get to understand and appreciate what you had.
As far as my three day weekend went, it was alright. I just relaxed, did the normal memorial day thing. Fiddled with flash more. Life is pretty darn dull.
I did get addicted to that new super mario brothers, though.
Maybe you deserve a vacation Tom.
Sometimes you gotta step back from a job or even a dream, to begin to understand why you love it so much. But that's the way I see things.
