" It is not enough for a surgeon to have the textbook knowledge of how to treat trauma victims—to understand the science of penetrating wounds, the damage they cause, the different approaches to diagnosis and treatment, the importance of acting quickly. One must also grasp the clinical reality, with its nuances of timing and sequence. One needs practice to achieve mastery, a body of experience before one achieves real success. And if what we are missing when we fail is individual skill, then what is needed is simply more training and practice. "
