Night Writer

I am a night owl. I hate mornings (the getting out of bed part...not the amazing sunrise part). All throughout high school and college I had trouble getting to bed at a decent hour and often overslept. When I had a baby, I was one of those awful moms that let her baby stay up later than 8pm...but the bonus was I didn't have a baby that woke before sunrise. ;o)

When I started writing my book, I had a tendency to write all night long. I went to bed as the sun was coming up and my early bird husband was going to work. It seemed crazy to other people (hi, mom!)...but for me, those were prime writing hours.  Writing during the day was just not the same...and writing in the morning was out of the question.  Everything just flowed better at night when the house was quiet (except for snoring) and there was nothing else to distract me from my writing.  

Everyone I know either claims to be a morning person (like my husband) or a night person.  My mother (a definite early bird) thinks I'm the only one who does this and that I am doing great detriment to myself by staying up all hours of the night. I try to tell her that it's not just me and it's ok as long as I'm getting 8 hours (and don't schedule any morning appointments)...but seriously, it's a waste of my breath.
I googled it and read studies that say early birds are not just annoyingly chirpy people in the morning, but happier overall...and they're more successful in business because their "chronotype" is more geared toward a corporate world.  However, we night owls might have some advantages...according to this article, "...studies reveal [night people] tend to be smarter and more creative than morning types, have a better sense of humor, and are more outgoing..."

But we are woefully out-of-sync with the corporate world.  I disagree that this makes us less successful.  It just means we pursue other avenues to success, and perhaps have a different definition of success than what this article implies.

What do you think?  Are you a morning or night person?  
Early bird or night owl?
And do you really think it matters?
