I fucking hate sleep. I work all day, get home and by the time I eat, get changed, and do a few errands I get maybe 2--3 hours to do whatever which fly by like 45 minutes. At that time, no matter how hard I try, my eyelids wont stay open and I think "well, I guess I ain't getting anymore out of this night, better admit defeat and go to sleep." Then in the morning, sleep feels so good[/I that I don't want to wake up. It's like some cruel joke. I know my body needs it and I don't deny it's refreshing, but at this point in my life it's hard not to look at sleep as anything other that an involuntary activity that wastes 1/3 of everyday I am alive. I guess some may say you would be bored staying up all night with everything closed and everyone asleep. I stay up until I can't stay awake any longer which is usually till about 2-3 am, and I would do the same thing If I didn't need sleep that I do now: practice guitar, write music, listen to music, play vidya, watch tv/movies,etc. Especially the music stuff since that's where my real passion is and what I think about all day at my job. I want to actually do something in my life with music and all that wasted time could be used for getting my shit together or hell, even getting a second job to help pay for the gear/equipment I need.
TLDR: Sleep.
