I'm starting to feel better!

Why is it that on the days that one wakes up and can't seem to get out of bed, so the whole morning is way off routine and simple things like choosing what to wear for the day gets thrown to the waste side so really, all one does is look in one's closet or drawers and comes up with something completely ridiculous or old or a combination of the two and then one puts that particular thing on (perhaps a red jumper from London circa 2008) and scrambles out the door in the morning and that happens to be the day that MULTIPLE people comment on how good that particular person looks?

How does that happen? And how do I replicate it for tomorrow?
