It always reminds me of one of my favourite quotes from Kahlil Gibran. I think it is wonderful that we can still be surprised by the birth and growth that takes place each spring.
"In a field I have watched an acorn, a thing so still and seemingly useless. And in the spring I have seen that acorn take roots and rise, the beginning of an oak tree, towards the sun.
Surely you would deem this a miracle, yet that miracle is wrought a thousand thousand times in the drowsiness of every autumn and the passion of every spring."
