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?
Besides the noble art of getting things done, there is the noble art of leaving things undone. The wisdom of life consists in the elimination of non-essentials.
It is not a daily increase, but a daily decrease. Hack away the unessential.
Life is really simple, but we insist on making it complicated.
