Because by doing so, we feel a sense of purpose. Of clarity. Of importance. Of community. And of belonging.
A sense of purpose in that we feel our lives have meaning.
A sense of clarity in that we know what direction we are going in.
A sense of importance in that we feel we are doing something of value.
A sense of community in that we share a special bond with others who believe and/or do the same thing/s that we do.
And of belonging in that we feel as though we are a part of something greater than ourselves.
