That's admirable. I certainly wish I did the same...
Well...
I am still a kid. I have this firm belief that adulthood is an experience, not a number. I'm still a child really.
But anyway, better late (17/18) than never, right Zach?
As for themes...
I certainly agree, but there's something that's been bothering me for a long time now and I got to ask if it's occurred to you also.
Have you ever wondered whether these themes are intentional or not? It's obvious that some authors do want to convey a certain message, but other times, it feels to me that the author simply wrote the story he wanted and the themes we connect with the narrative are a consequence of the author's unconscious mind working the story he wants to write.
For instance, let's use a more obvious piece of work which relates to capitalism and the American Dream as well as other topics: Death of a Salesman. The play is obviously intended as a critique of society and capitalist culture but something tells me that the inner workings of Willy Loman's subconscious is something totally unintended but just as deep and meaningful.
However, back on topic.
Whilst I agree that underlining themes are certainly vital to the quality of any work of art or literature, what I get most of a story is the story itself and the characters that come with it. It's far more superficial I know, but it's always the first impression I get before my mind goes into analysis mode.
