I don't think I know anyone who doesn't have at least one thing they are rather vain about.
One of my guy friends is quite vain about his wardrobe. He prides himself on being different and unique with his clothing choices. No worries there...he nails it on a daily basis. Whether his selections are embraced or mocked, he stands apart from the crowd. For him, that's the mark of dressing for success.
One of my girlfriends is completely vain about her hair. She doesn't go a month without it being perfectly colored and cut. The amount of money she spends on hair maintenance could rebuild Haiti, but this is the indulgence that makes her feel great about her outward appearance.
I know another who take his vanity to the extreme. He is so proud of his body - one that he's worked incredibly hard for, mind you - that he insists on walking the earth shirtless whenever possible. It's not unrealistic to see him walking the streets of Boston sans shirt. Considered excessive by most, in his mind, if you've got it, flaunt it.
And me, I'd say my vanity is my fingernails. I grew my nails out when I was a junior in high school. Someone told me I had stubby fingers, and the comment stung. My fingers were obviously never going to grow longer, but growing my nails long gave the illusion of sporting stilettos on my digits. And I was hooked.
I have now had long nails for almost 30 years. Many people assume they are fake, but they are not. (Quick trick to tell fake nails from real ones: Turn the hand over. With fake nails, you can actually see the real nail growing along underneath the fake one.) There are lots of things I should be more vain about. I should get my hair cut more often than I do. If I listened to my mom, I should where lipstick to brighten up my face. And while I do my best to look pulled together everyday, it is ultimately my nails which I invest most in. Why?
I think it goes beyond thinking I have stubby fingers. Getting my nails done every two weeks ensures that I have a solid 45 minutes of uninterrupted time. I chose a place where the people who work there speak very limited English, so aside from the friendly pleasantries, they leave me alone to be one with my thoughts. I will read. I will listen to music. I will create in my mind. That time is precious to me, because it is such a rarity in my life. And at the end of it, I have pretty hands as a side bonus.
No matter what lifestyle we lead, can probably zero in on at least one quirky vanity that makes us, us. For whatever reason, that thing makes us feel good about ourselves, and allows us to take a certain pride. Some may be superficial like clothing, hair, body or nails. Others may be more cerebral such as a unique talent or skill that one wears as a mark of his or her own brand of greatness. Whatever yours is, rock it. While no one loves a narcissist, having "your special thing" that makes you feel good about yourself can be a healthy form of self-expression.
