We all need relationships that give us the feeling of ecstasy we get from life's simple moments—the first sip of coffee, the smell of fresh laundry, a hot shower in the winter, a movie with a good ending, and a glass of water after an intense workout. Sometimes, we can't describe the type of people we need in our lives through a list of attributes. Sometimes, it’s simply the vibrations they give us—ones that make every cell in our body dance.
