When I have a very strict schedule, I can be a morning person. I can actually tolerate, and even enjoy, being up in the morning and having the whole day ahead of me. There is a really great feeling when you're wide awake and its like 7:30 and you've had a shower and the sun is just warm and shining through the windows.
However, I always end up breaking the schedule by staying up late. I really do prefer being a night owl, I guess, though it isn't always convenient now that I can't ever sleep in. (The joys of being a parent.)
