I come from a family of beautiful women. My mother was a beautiful movie star and I can't compare to her. However, I've been told I'm pretty. I still feel that I'm not good enough. I wonder if I'm being ungrateful or greedy. Below is a picture of my mom just to give you an idea of what I'm being compared to.
I know exactly how you feel. It's weird, because I love myself and have really high self-esteem, but I still know there's room for improvement. That's why I do what I can to look good, I eat right and spend about 10 hours a week in the gym. Lifting weights and being fit is a huge self-esteem booster, and makes me feel way hotter than I did before I started.
