“It just shows you.”
The schedule Gatsby’s father discovers exemplifies the sheer will-power and self-control Gatsby possessed. Gatsby’s rigid schedule speaks for itself and “just shows” that Gatsby was willing to do whatever it took to fulfill his desires—to become “great” by his lights.
Although it is true that Gatsby’s motivation to change himself was externally influenced by the expectations of society, all in all, Gatsby also had a burning internal desire to be the most successful person he could be. The schedule is evidence that, long before he met Daisy, he was willing to regiment his life in order to improve himself and attain his dreams.
