I'm a night person. I always have been and probably always will be. I love the night time. I love the spaciousness and quiet. This is when I work the best and come up with my better ideas.
However, socially speaking to be a night owl is not the way to go. In fact, most vocations will bend its workers into morning people by necessity. This is neither good nor bad. It just is.
But it is worth mentioning that there is nothing wrong with being up late at night; or during the day; or in the cold; or in the heat. We are all different and all thrive under different conditions.
So I would advise anyone to embrace their comfort zone, not fight it. Analyze your workspace and really figure out what it may need to put you in the right frame of mind. It may be the lighting, the furniture, the clutter, whatever. But never underestimate the effects - both good and bad - that these things can have on your productivity.
Now if you'll excuse me, 7-Eleven is calling me.
