I went to the woods because I wished to live deliberately.

How can we remember our ignorance, which our growth requires, when we are using our knowledge all the time?

I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived. I did not wish to live what was not life, living is so dear; nor did I wish to practise resignation, unless it was quite necessary. I wanted to live deep and suck out all the marrow of life, to live so sturdily and Spartan-like as to put to rout all that was not life, to cut a broad swath and shave close, to drive life into a corner, and reduce it to its lowest terms.

The gentle rain which waters my beans and keeps me in the house today is not drear and melancholy, but good for me too. Though it prevents my hoeing them, it is of far more worth than my hoeing. If it should continue so long as to cause the seeds to rot in the ground and destroy the potatoes in the low lands, it would still be good for the grass on the uplands, and, being good for the grass, would be good for me, too.

I can alter my life by altering my attitude. He who would have nothing to do with thorns must never attempt to gather flowers.

When a dog runs at you, whistle for him.

The little things in life are as interesting as the big ones.
