(not a photo of myself)
But when they're 60years old, sitting around looking at old pictures. They will always say "I wish I still had...". No matter what. So be happy with what you have, because later on you will wish you had it back.
I am very well aware of the fact that I dye my hair different colors, I change my wardrobe because of the seasons, and diet to lose a few pounds. But in the end, I will never go get plastic surgery when I'm a few years older. I want to be an elder with laugh lines and crows feet, so when my grand-kids see me, they know I was happy in my life.
