Good-bye, proud world! I'm going home: Thou art not my friend, and I'm not thine. - Ralph Waldo Emerson

At times the whole world seems to be in conspiracy to importune you with emphatic trifles. Friend, client, child, sickness, fear, want, charity, all knock at once at thy closet door and say, — 'Come out unto us.' But keep thy state; come not into their confusion. The power men possess to annoy me I give them by a weak curiosity. No man can come near me but through my act.

What is the hardest task in the world? To think.

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.
