Until you grow up. And you realize that anyone with money can have what you have and it's all vanity and ego. Is it just all a different version of the girl who wears a bunch of slutty makeup or the guy with the hair and the tan and the car? Is it vanity masked by words that make it seem less douchey like "hard work" and "dedication"? Is having abs gonna boost your confidence or get you closer to banging the person you feel you deserve to be banging? It'll make you more desirable for a time, only if your face isn't a disaster, but you'll age and then it's gone. I'd say do it for health and functional purposes, but avoid trying to satisfy yourself with something that can be easily bought.
