A common conceptualization of us humans is that we have four dimensions: mind, body, emotion/heart, and spirit.
Our best selves are manifested when we employ all four dimensions into our endeavors. It is from such integrated and holistic enrollment that we experience wholeness and self-actualization.
However, it is often the case that we bring only two of those dimensions to our workplace: mind and body. When we do that we have robbed ourselves and our vocation/profession of the very drivers of creativity, innovation, and service - the emotion/heart and the spirit.
When we invest only our mind (i.e., knowledge) and our body (i.e., physical structure) into our work, we allow ourselves to become little more than automatons or machines. In essence, we simply function as robots, in the business of "manufacturing."
We can do, and be, so much more.
