Hypocrisy is the most difficult and nerve-racking vice that any man can pursue it needs an unceasing vigilance and a rare detachment of spirit. It cannot, like adultery or gluttony, be practiced at spare moments it is a whole-time job. W. Somerset Maugham
Guard well your spare moments. They are like uncut diamonds. Discard them and their value will never be known. Improve them and they will become the brightest gems in a useful life. Ralph Waldo Emerson
