Sexy Self Esteem-Raising Strategy

I have low self esteem. I'm trying to combat it, but it's not the easiest thing in the world- especially on days like today where my hair is messy and my clothes are dirty and I could really just use a good shower.
How can I look myself in the mirror right now, as grungy as I look, and say "You're beautiful" to my reflection?

I can't. At least, I can't say it and mean it. If I can't say it and mean it, then I certainly can't believe it.
So I don't bother trying to.

Instead, I break out the exhibitionist in me and take a slightly different route...
