My sister, Ellen, is one of the most positive people I know. She's very driven, extremely smart, very much an extrovert, and her attention to detail and excellence is legendary at home and at work. The one thing that she does almost all the time is demonstrate a positive attitude. She has a big job with many responsibilities and stresses, but she still tries every day to radiate joyous energy. I think this is one of her gifts to the world.
