“Make the most of your regrets; never smother your sorrow, but tend and cherish it till it comes to have a separate and integral interest. To regret deeply is to live afresh.”

American transcendentalist writer and naturalist of the mid-19th century, Thoreau is best known for his philosophical essays and his two-year experiment in simple living at Walden Pond. His work bridges practical observation of nature with deep reflection on individualism, civil disobedience, and the importance of living deliberately.
