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?
Methinks that the moment my legs begin to move, my thoughts begin to flow.
Life is really simple, but we insist on making it complicated.
You see how few things you have to do to live a satisfying and reverent life? If you can manage this, that's all even the gods can ask of you.
If you wish to have leisure for your mind, either be a poor man, or resemble a poor man. Study cannot be helpful unless you take pains to live simply; and living simply is voluntary poverty.
