What a gift from writer Dana Manciagli to share with us. Her twin sister, Tracy, lost her fight against breast cancer in May of this year, an during that time Dana says that Tracy taught her a lot. Dana says that her sister did not like for her to use the word "should". Using it seems to put up a lot of road blocks in life, in both personal and business matters. And what an interesting view her sister had on karma. Take a look at what she had to say.
