None of us will ever accomplish anything excellent or commanding except when he listens to this whisper which is heard by him alone. - Ralph Waldo Emerson

To accomplish excellence or anything outstanding, you must listen to that whisper which is heard by you alone.

Trust thyself: every heart vibrates to that iron string.
Nothing is at last sacred but the integrity of your own mind. A man should learn to detect and watch that gleam of light which flashes across his mind from within, more than the lustre of the firmament of bards and sages... In every work of genius we recognize our own rejected thoughts: they come back to us with a certain alienated majesty.
The power which resides in him is new in nature, and none but he knows what that is which he can do, nor does he know until he has tried

We dress our garden, eat our dinners, discuss the household with our wives, and these things make no impression, are forgotten next week; but in the solitude to which every man is always returning, he has a sanity and revelations, which in his passage into new worlds he will carry with him. Never mind the ridicule, never mind the defeat: up again, old heart! — it seems to say, — there is victory yet for all justice; and the true romance which the world exists to realize, will be the transformation of genius into practical power.

Truth is the summit of being; justice is the application of it to affairs.
