“The key differentiator, then, between happy high achievers and the rest is that happy high achievers are extremely vigilant about only allowing relationships into their lives that add to their energy. This includes their marriages as well as their relationships with their families, companies, boards of directors, key staff, and important clients. They make it a point to only allow relationships that are net additive. If a relationship isn’t net additive, it’s no longer one of their primary relationships. It gets shifted or it is gone.”
