Whenever I have
found out that I have blundered, or that my work has been imperfect,
and when I have been contemptuously criticised, and even when I have
been overpraised, so that I have felt mortified,
it has been my greatest comfort to say hundreds of times to myself
that
"I have worked as hard and as well as I could, and no man can do more
than this".
I remember when in Good Success Bay, in Tierra del Fuego, thinking
(and, I believe, that I wrote home to the effect) that
I could not employ my life better than in adding a little to Natural
Science
