I'm tired

I think I've written before about my intense fear/dislike of being a trainer at work. Today and tomorrow, I'm teaching a couple of people how to use our knowledgebase software. This isn't a big deal--one of the people was on my team when I started, so I've known her for five years. The other guy I've known for a few years, too. I know this software backwards and forwards. Every rational bone in my body told me that this wouldn't be a big deal. Now that the first day is over, I know it's not bad at all. But last night, some part of me sure didn't believe any of this. I slept for an hour, woke up, and then laid in bed until sometime after 2:30. Considering I get up a little after 5:00, that means I barely got more than 3 hours of sleep last night. This is not a good thing. Why am I still awake right now, you ask? I have no idea. On that note, I'm going to bed.
