I'm a night owl. That's why I'm up late!
Me too! I wish I were an early bird though. I would love to be able to wake up early
I'm not so sure. Mornings are a bit overrated. 
I work during the day though and I have a hard time adapting to standard day-time working hours because I'm a night owl
Yeah I always have to tell myself that to go to bed once it gets to midnight. 
Maybe you have a delayed sleep-phase disorder, as many night owls do
What is that?
It's a disorder that causes great difficulty adopting normal sleeping and waking times
What causes it?
A chronic dysregulation of a person's circadian rhythm causes it
