Experiencing "let-down" after success:

I don’t know why it is, but often we experience a big “let-down” right after a big success. You get a degree, or finish a project, or land a big promotion, or win a big award or make a big purchase --- you complete some major goal. And then you have that depressed feeling like “Is that all there is…?” That’s why young women are warned to expect some degree of “Post-natal depression” right after the birth of a baby. That’s why Retirees need to be ready for a sense of let-down after they are finally able to retire.
