We are wired for interpersonal attachments. It is a fundamental human motivation and is incredibly powerful. We work best as humans (as well as employees) when we have frequent interactions with people with whom we have an ongoing bond.
Belonging somewhere has multiple strong effects on emotional patterns and cognitive processes. A lack of attachment causes pain, increases our perception of stress, impairs cognitive functioning and can interfere with the immune response.
As a leader, boss or friend you have a opportunity to be a role model in building real and valuable relationships.
Consider being open, honest and transparent in your interactions with people.
Rather than sharing just the bear minimum, share deeply.
