If there's one thing in life I hate, it's waiting. Waiting for anything, really; it doesn't especially matter what.
The problem is, waiting makes me doubt. Right now, I'm waiting for the bus. I got to the stop before it was scheduled to arrive, but it's a few minutes past now. And all I can think is, "what if it just arrived a few minutes early, and I'm standing here for no reason?"
Of course, this is pretty silly — I never pretended it wasn't. The bus will come, and Sarah will come home from her trip, and I'll give the presentation on Monday (whether or not John ever remembers to bring in the presentation remote he said he was going to loan me). All of these good things will happen, and more, and all my doubts will be shown for what they are: just stupid fears without basis in reality.
But for now, I wait.
