Not what YOU think are your best traits; that's not as interesting and could be biased. No, what other people have complimented you on, thus they must be true if others see it in you. Anything. Physical, personality, skill, etc. And feel free to add to them. I'll start with something basic. My hair. I've never been bald and to this day have a ton of dark brown hair. When I was a child, for as long as I can remember women have lamented how jealous they were of my hair. So, I guess a lot of people like it.
