Don't underestimate body language. We speak loud and clear without words.. A friend of mine who is intelligent, witty, successful, and very nice, far better a person than I, told me years later that she hated that I made friends easily when we were younger. She said that people would come up to me and want to be my friend. She didn't think back at how she was tho - she would be sitting in a corner of the pub, body language showed she was closed and wary. She is a great friend, but she was more suspicious than I and it took her longer than I to trust people. I was always friendly, open and always smiling in my youth. This is attractive to others, always was, always will be, and nothing about me being a better person.

Envy, being wary, lack of confidence, shyness - all these things we show in our body language.
