Sometimes we are devils to ourselves When we will tempt the frailty of our powers, Presuming on their changeful potency.
William ShakespeareAntonio: Will you stay no longer? nor will you not that I go with you? Sebastian: By your patience, no. My stars shine darkly over me; the malignancy of my fate might, perhaps, distemper yours; therefore I shall crave of you your leave that I may bear my evils alone. It were a bad recompense for your love to lay any of them on you.
William Shakespeare
