A man is rich in proportion to the number of things which he can afford to let alone.
I am no more lonely than the loon in the pond that laughs so loud, or than Walden Pond itself. I am no more lonely than a single mullein or dandelion in a pasture, or a bean leaf, or a housefly, or a bumblebee. I am no more lonely than the Mill Brook, or a weathercock, or the north star, or the south wind, or an April shower, or a January thaw, or the first spider in a new house.
In my walks I would fain return to my senses. What business have I in the woods, if I am thinking of something out of the woods?
An old silent pond. A frog jumps into the pond — splash! Silence again.
There is a pleasure in the pathless woods, there is a rapture on the lonely shore, there is society where none intrudes, by the deep sea, and music in its roar: I love not Man the less, but Nature more.
The woods are lovely, dark and deep, / But I have promises to keep, / And miles to go before I sleep, / And miles to go before I sleep.
