In the history of the individual is always an account of his condition, and he knows himself to be a party to his present estate.
Ralph Waldo EmersonLife is in short cycles or periods; we are quickly tired, but we have rapid rallies. A man is spent by his work, starved, prostrate; he will not lift his hand to save his life; he can never think more. He sinks into deep sleep and wakes with renewed youth, with hope, courage, fertile in resources, and keen for daring adventure.
Ralph Waldo Emerson
