Many observers argue that careers are less predictable than they once were, due to the fast pace of economic and technological change. This means that career management is more obviously the responsibility of the individual rather than his or her employing organisation, because a "job for life" is a thing of the past. This has put more emphasis on subjective criteria of career success. These include job satisfaction, career satisfaction, work-life balance, a sense of personal achievement, and attaining work that is consistent with one's personal values. A person's assessment of his or her career success is likely to be influenced by social comparisons, such as how well family members, friends, or contemporaries at school or college have done.
