Alright, here I'm sitting, at like 10:30 PM, Swedish time.
I'm gonna get up at about 8:00 AM tomorrow, but I really don't feel like going to sleep yet, oh noes, I'm gonna stay up for just a little while longer.
When I get home to my apartment, I'm gonna play some Final Fantasy 6, as usual, and then read a few chapters in The Silmarillion () before actually sleeping.

I mean, I don't take sleep too seriously, and I like it.
Instead of feeling like "OMG, gotta sleep when I get home!", it's more like "I'll sleep soon, but FIRST, I'm gonna play some games and whatnot, yay".
I don't feel so damn restricted because of some unwritten "sleeping rule", and it actually feels much better.
Sometimes I can just stay up all night and sleep whenever I have time for it, whatever.

Do you have this attitude as well?
