My answer to What should I base success on?
Answer by Ken Larson:
Fulfillment of your value system.
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.
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.
Human intellect is an ever restless endeavor and we struggle to evolve in other aspects fast enough to adapt to our technology.
We are sensitive and vulnerable creatures, designed in a complex and vastly varying ways. The pace of life these days requires cultivation of expectation management and everyone must evolve their own unique form of that art to achieve their individual success.
