I who cannot stay in my chamber for a single day without acquiring some rust, and when sometimes I have stolen forth for a walk at the eleventh hour of four o’clock in the afternoon, too late to redeem the day, when the shades of night were already beginning to be mingled with the day-light — have felt as if I had committed some sin to be atoned for, I confess that I am astonished at the power of endurance — to say nothing of the moral insensibility of my neighbors who confine themselves to shops and offices the whole day for weeks and months, aye and years almost together. I know not what manner of stuff they are of — sitting there now at three o’clock in the afternoon, as if it were three o’clock in the morning. Bonaparte may talk of the three o’clock in the morning courage, but it is nothing to the courage which can sit down cheerfully at this hour in the afternoon over against one’s self whom you have known all the morning, to starve out a garrison to whom you are bound by such strong ties of sympathy. I wonder that about these times, or say between four and five o’clock in the afternoon, too late for the morning papers and too early for the evening ones, there is not a general explosion heard up and down the street, scattering a legion of antiquated and house-bred notions and whims to the four winds for an airing — and so the evil cure itself.

It would seem that I 'suffer' the same affliction as Thoreau. The past three days, I have walked "through the woods and over the hills and fields" surrounding our fair village three-and-a-half, three-and-a-half, and four hours, respectively. No less would do, and more would have done nicely. I, likewise, share in the sinful "eleventh hour of four o’clock in the afternoon" scenario for which I feel I must atone. If only my affliction would spread to span the breadth and depth of his, my hero's, genius.
But if one will read Thoreau's first few Journal entries, written when he was twenty (in response to Emerson's having asked him if he kept a journal), you shall see that his genius was very much intact at that tender age.
