"I don't know how I do it, I really don't"

In this quote, Pete Sampras expresses a sense of disbelief and unpredictability about his own capabilities. He acknowledges that he has the ability to accomplish great things, but he is not able to explain how he does it. This could be analyzed as a humble declaration, as Sampras does not want to take credit for his success or boast about his skills. It could likewise recommend that he is continuously pressing himself to enhance and reach brand-new heights, and even he is shocked by his own achievements. In general, this quote highlights the complexity and mystery of skill and success, and the humbleness and determination of a true champion.
