Here's what I've learned:
You will never accurately estimate how cute you are in a given day. This can be easily proven with a sneaky and/or ambush photograph taken of you by some jerk (let's call them, Your Husband...or Your Nerdy Co-Worker Who Can't Keep His Hands Off His iPhone,...or A Toddler High On Pixie Stix) who doesn't have the decency to give you a respectable lead time for preparing your angles and whatnot before snapping away.
Once you see this photo (and you WILL see it, because the aforementioned jerk ALWAYS wants to show off his work immediately and to anyone within a quarter mile), you will either be pleasantly surprised by a perfect curl or glowing skin...or deeply horrified by your miserly posture, sickly pallor, wonky eye, random bulging area, gigantic squirrel cheeks, shockingly flat hair, phantom zit, etc., etc., etc.
No matter which way that glorious wind blows, your own estimation of your cuteness will never - not in the slightest - be remotely correct.
