It is the experience of thriving, of having everything you need all around you. It is the feeling of self-respect, the process of self-actualization, the constancy of self-expression. It is the knowledge that you are making the contribution you are designed to make. It is the security that comes from knowing that you are worthwhile, that you are contributing to those around you enough that you will always be included and appreciated.
Do you know that your employer wants this for you also? Why? Because most companies do care about their people; companies are composed of people after all. Business leaders know that people who are engaged in their work are more likely to be strong performers.
