"If you hold to Nature, to the simplicity that is in her, to the small detail that scarcely one man sees, which can so unexpectedly grow into something great and boundless; if you have this love for insignificant things and seek, simply as one who serves, to win the confidence of what seems to be poor: then everything will become easier for you, more coherent and somehow more conciliatory, not perhaps in the understanding, which lags wondering behind, but in your innermost consciousnesss, wakefulness and knowing."
-from "Letters to a Young Poet"
