Discussion: I'm a 16-year-old girl. I'm skinny, short, not pretty, and not as sexy as other girls my age. Jealousy eats me from the inside out.

Jealousy is a natural emotion in all of us—evolutionarily designed to develop the instinct for competitiveness that pushes people to achieve. You will be surprised to know those lovely people have other problems, no less troublesome. There is no perfection in anyone. You should develop your abilities, in which you have a relative advantage. You will be surprised to hear that the unattractive girls from high school often flourished in adulthood and became beautiful women, no less "the queen of the class." Put the energies of jealousy in the direction of your empowerment, and you will see that you are no less successful than the most beautiful.
