 " Not one man in a thousand has the accuracy of 
   eye and judgment sufficient to become an eminent

   If gifted with these qualities, and he studies his
  subject for years, and devotes his lifetime to it with
  an indomitable perseverance, he will succeed, and
  may make great improvements; if he wants in any of
  these qualities, he will assuredly fail."

Charles Darwin, Origin of The Species, 1859
