Motivation at the Wrong Time!

Seriously... right now it's 10:15 pm and I want to run. Really badly.

This always happens to me! I am motivated to exercise at the weirdest times! Oh and I have a paper to write too (stalling.... stalling....) but I can't stop thinking about running. Then what happens is tomorrow, I will try to run during the day and I won't be motivated! Argg! I wish I belonged to a gym that was open late... but I'm broke so I can't belong to one. I would run outside but I don't exactly live in the best of neighborhoods.

Does this happen to anyone else?
