"... the meaning of success has also changed for most people. No longer do people think of success in terms only in the vertical terms (for example in terms of promotion). Increasingly, people define success in their own terms, measured against their own particular set of goals and values in life. We call this psychological success. The good thing about success from the individuals point of view is while there is only one way to achieve vertical success (that of moving up), there are an infinite variety of ways of achieving psychological success."
