How did fitzgerald draw on his own life experiences to create his characters and plot lines?

One could contend that Fitzgerald composed the plot the way he did with the expectation of mirroring his perspective of an awesome disquietude defeating American culture; a plot that uncovered a pervasive vacuousness that debilitates to degrade cultivated men and ladies. This is maybe a demeanor encouraged by Victorian culture, brought into the new century. With that in mind, maybe the novel ought to have been entitled "The Troubled Twenties".
