In chapter 9 of The Great Gatsby, what does young James' schedule reveal about himself?

James Gatz' schedule as a young boy reveals several things
to the reader. First, it reveals that he had an 8 hour a day credible job. This is
something we don't see in the book. Second, it reveals that before and after work, he
made the effort to improve himself mentally and physically. Finally, it demonstrated he
had resolves which meant improving himself morally. He specifically chose not to smoke
or chew. He wanted to improve his treatment of his parents. He wanted to have good
hygiene and save his money.

These resolves certainly
display the man we see on the outside when we meet Jay Gatsby, but the man on the inside
must be different.
