“Every industrious man, in every lawful calling, is a useful man. And one principal reason why men are so often useless is that they neglect their own profession or calling, and divide and shift their attention among a multiplicity of objects and pursuits.”

American essayist and poet of the 19th century, Emerson is best known for his transcendentalist philosophy and influential lectures on self-reliance and individualism. His works, including "Self-Reliance" and "Nature," championed intuition, personal experience, and the inherent goodness of humanity.
