I'm pretty much an all day kind of guy. I mean they all have their ups and downs, but waking up early and staying up late in the midst hours of the night don't bother me all that much. In the morning, once I have my eyes open I can't go back to bed, so I end up starting my day regardless of the time. However, I can say too early is a different story, but that ranges from two to five in the morning. As for the night, I can wake up as late as possible and I'll still be the calm cool person you see all day. Yeah, I'll get tired if I've had a busy or rough day, but my mood doesn't change. So, no time of the day is specifically meant for me, it just depends on what may happen during that day that can get to me.
