Pitt describes a career in which successful and unsuccessful projects are both to be expected. Drawing on thirty years of experience, he suggests that neither outcome deserves prolonged attention at the expense of continuing to work. His emphasis is on the ongoing practice of storytelling, rather than the results of any single project.

The phrase “either one” matters: his advice concerns success as well as failure. Dwelling on achievement can become a distraction from the next project, just as dwelling on disappointment can. He presents persistence as a practical response to the uneven results of creative work, not as a guarantee of eventual success.

This need not mean dismissing evaluation or learning from mistakes. The distinction is between useful reflection and remaining preoccupied with an outcome. More broadly, the quotation suggests maintaining a sense of purpose that does not depend entirely on whether the latest effort succeeds.
