I always think of this poem this time of year. It is so lovely and so true. (Thank you high school English for instilling this poem in my brain.)
Nature's first green is gold, Her hardest hue to hold. Her early leafs a flower; But only so an hour. Then leaf subsides to leaf. So Eden sank to grief, So dawn goes down to day. Nothing gold can stay.
