Tranqility is a certain quality of mind, which no condition or fortune can either exalt or depress.
Seneca the YoungerSolitude and company may be allowed to take their turns: the one creates in us the love of mankind, the other that of ourselves; solitude relieves us when we are sick of company, and conversation when we are weary of being alone, so that the one cures the other. There is no man so miserable as he that is at a loss how to use his time
Seneca the Younger
