Sore Muscles

My arms and back are sore, and I love it. There's nothing like stretching out and feeling yesterday's workout. But ironically enough, the same sensation of soreness can be awfully unpleasant when it results from sleeping on the ground or in a strange position.

I wish sleep deprivation worked the same way as muscle exhaustion. When you stay up late doing something fun and exciting or wake up early to do something constructive, the resulting tiredness would be gratifying. If that were the case, my droopy eyelids would feel so good right now.
