Henry David Thoreau said this quote

Sometimes, in a summer morning,having taken my accustomed bath, I sat in my sunny doorway from sunrisetill noon, rapt in a revery, amidst the pines and hickories and sumachs,in undisturbed solitude and stillness, while the birds sing around orflitted noiseless through the house, until by the sun falling in atmy west window, or the noise of some traveller's wagon on the distanthighway, I was reminded of the lapse of time. I grew in those seasonslike corn in the night, and they were far better than any work of thehands would have been. They were not time subtracted from my life, butso much over and above my usual allowance. I realized what the Orientalsmean by contemplation and the forsaking of works. For the most part, Iminded not how the hours went. The day advanced as if to light somework of mine; it was morning, and lo, now it is evening, and nothingmemorable is accomplished.
