Did you ever wonder why all the see-sawing? Why all the mental battles? Why all the craziness? For me... I think it has a lot to do with sleep (as I write this at 12:30) and stress levels. But... mostly sleep. Lack of sleep, for me, leads to bad decisions (about food and otherwise), stress, and frustration... Overall, there isn't a single positive redeeming factor of staying up for the sake of staying up.
That said, I think I know why I do it (and, ok, I'm already backpedaling on the "no redeeming factor" statement). I think it is the only time in my life (between the hours of 11:30 and 1:00) that I get to myself. So... effectively, I sacrifice sleep for time in my own head. Good trade-off? Not always. But, I think it's important. Here's the point in my own post where I totally flip-flop my opinion.... Actually, despite the long list of negatives, I think I need it.
Where does that leave me? Eh... right where I was five minutes ago. But... just like the time I spend on the road running, 11:30-1 is the time that I pick to unwind. The only difference is... that time is truly "off the clock" (ironic huh?). I have no goals, no pressures, no anything. I think we all need a little more of that at times.
