" I think it is a very common error among the well, to think that "with a little more self control"
the sick might, if they choose, "dismiss painful thoughts" which "aggravate their disease."
Believe me, almost any sick person who behaves decently well, exercises more self-control every moment of their
day than you will ever know until YOU are sick yourself. Almost every step that crosses their room is painful to
them; almost every thought that crosses the brain is painful; and if they can speak without being savage, and look
without being unpleasant, they are exercising the utmost self-control. " Florence Nightingale
