The most significant meaning we can take away from "Nothing Gold Can Stay" is that, well, nothing gold can stay. Let's face it: the most beautiful things in life often have the least longevity. The poem uses the examples of spring blooms, the Garden of Eden, and sunrise to get this point across, leaving us to think about all the things in our lives that are so wonderful and so transient. Whether it's the euphoria of winning a soccer game, or the youth of our minds and bodies, we've all experienced something wonderful that has faded away incredibly fast. Ah, the inevitable bummer.
The whole point of this poem is to demonstrate that the most wonderful things about life are also the most transient.
Nothing gold can stay? My foot. Hasn't Frost heard of unconditional love?
