When I was in high school I’d stay up until 4 or 5 a.m.  almost every weekend.  It was also not uncommon for me to sleep until one or two in the afternoon.  However, now that I’ve gotten a little older my concept of time has drastically changed.  The other night I looked at the clock and realized it was almost midnight and my first thought was "What am I doing up so late?"  haha.  What’s more is if I’m not up by eight in the morning I feel like I’ve wasted the whole day.  Kind of strange how much your perception of things can change in ten years.
