"Just be yourself" This is pretty similar to what i remember reading as a teenager when looking for advice on the opposite sex. Though no one ever really told me, how to be me.
There are lots of me's, the one that stays up late watching south park, and the one that enjoys a fine glass of wine. Many of my friends took this phrase as a ticket to be slovenly, thinking that they would attract others by "being themselves". While the advice is sound, it shouldn't be taken as an absolute law.
