"Only those who will risk going too far can possibly find out how far one can go"
-- T.S. Eliot.

"Labor not as one who is wretched, nor yet as one who would be pitied or admired.  Direct yourself to one thing only, to put yourself in motion and to check yourself at all times."
-- Marcus Aurelius- Meditations

"For though we are made especially for the sake of one another, still each of us has his own tasks.  Otherwise another's faults would harm me, which God has not willed, in order that my happiness may not depend on another."
-- Marcus Aurelius, Meditations, paraphrased

"Whoever is out of patience is out of possession of his soul.  Men must not turn into bees who kill themselves in stinging others."
-- Jonathan Swift
