Random Thoughts: Feeling "Off"

It's strange. I don't feel sick. I don't really feel all that tired. Everything seems to be in full functioning order, but for some reason I feel "off." I don't really know what it is, but I can most compare this feeling to my preflight state of mind.

I enjoy flying. I am perfectly content to sit and people-watch for long periods of time. I love the fact that I can walk into a metal and plastic cylinder and a few hours later walk out on the other side of the world to see new and different things. Where I encounter my problems is getting to the airport. I don't know why, but for some reason I have this overwhelming anxiety that I will miss my flight. Have I ever missed a flight? No. Never. Not even close. Does that matter? Apparently not. I move around in a blur, talk very fast, drive very fast, walk very fast, and get jumpy standing in line very slowly. I bug the hell out of my wife with this personality "feature."

Anyway, I guess that defines the feeling that I have right now. I am feeling anxious. Why? Maybe it's sleep deprivation. I did wake up at 4:00 a.m. Should I call home and make sure Erin and Laura are OK? I'm sure they're fine. It's me that has the problem. Maybe I left the coffee pot on, even though I didn't (and wouldn't) turn it on in the first place. Actually, come to think of it, we don't even have a coffee pot. Well, I guess everything is OK then.  So, why do I feel like this?
