"An author ought to write for the youth of his own generation, the critics of the next, and the schoolmaster of ever afterwards"

F. Scott Fitzgerald's quote suggests that authors ought to write for the youth of their own generation, as they are the ones who will be most affected by the stories and messages in the works. The author should likewise consider the critics of the next generation, as they will be the ones to judge the work and identify its lasting legacy. Finally, the author ought to think about the schoolmaster of ever afterwards, as their work might be studied and evaluated for generations to come. This quote stresses the value of composing for today, while also considering the impact of the work on future generations. It is a reminder that authors need to strive to produce works that will stand the test of time and be kept in mind for several years to come.
