Packing Instructions

When packing for travel the paranoia creeps in the night before: I'm going to forget something. I've found the easiest thing to combat this irrational fear is a dose of common sense, so I pack everything the night before. But what about my cell phone charger? I want to use it overnight so my phone is fully charged for the flight, but now I've tasked myself with remembering to pack something important in the delirium of tomorrow's early morning. That's to say nothing of the toothbrush I will have to use then pack when I wake up. That I could buy both of these items in any gas station or airport in the world does nothing to alleviate the concern, after all it's impossible to argue with someone whose concerns are utterly baseless--especially when it's yourself.
