“Our doubts are traitors,
and make us lose the good we oft might win,
by fearing to attempt.”
William Shakespeare, Measure for Measure
“Optimism, not pessimism, is needed in medicine; not, however, the optimism that takes up each new fad to the exclusion of old and tried measures, but the kind that begets hopefulness and confidence.”
