Most successes are built on enterprises that have goals, objectives and missions consistent with the founders value system. That consistency brings a great deal of personal peace, even when the challenges are tough. Why?
Because our existence and our mental universe are driven by factors that we as individuals inherit through the gene pool, as enhanced by our experiences in life. The result is our personal value system. It is the most precious thing we own.
In short we are most at peace when we are in sync with the personal value system that has evolved as a result of the above factors and when we are permitted to pursue our values in our personal and professional endeavors.
If we cannot achieve that harmony we will seek change.
