I went indoor rock climbing yesterday. I'm scared of heights. It was terrifying. But, since I did it with guys from work, I forced myself to get to the top mostly because my fear of humiliation outweighed my fear of heights. Similarly, it's been very cold lately in Chicago. Some days I whine when I walk outside. The next day it could be the exact same temperature, and I'm fine. So, obviously, my mental state has a large control over my emotions and behavior. And my question is, how do I conquer these things? Force myself to climb up a mountain? Sit outside in the cold? How do I get control over my mind?

I wake up tired every morning. I'm tired at work. I usually wake up a little during lunch. Then, I'm really tired in the afternoon. Then, I'm awake for dinner, and am tired again until it's time for bed. I probably get an average amount of sleep compared to most Americans. And yet I spend most of my life tired. Is this normal? natural? a recent historical trend? It just doesn't seem right. Or should I just compare it to eating? Where I'm always hungry. But, it's a controllable hunger.
