What person (real or fictional) comes to mind, for you, as the ultimate picture of success? What specific accomplishment or attainment of theirs stands out for you as the key symbol of their success? To put it another way, what specific thing stands as the undeniable proof that they are indeed successful?
Now, would this same specific thing work as a measure of success for you? Or would your own ideal success lead in a different direction and take a different physical form?
