Anglers! Heed thee word!

"In angling, as in all other recreations into which excitement enters, we have to be on our guard, so that we can at any moment throw a weight of self-control into the scale against misfortune; and happily we can study to some purpose, both to increase our pleasure in success and to lessen our distress caused by what goes ill. It is not only in cases of great disasters, however, that the angler needs self-control. He is perpetually called upon to use it to withstand small exasperations."
—SIR EDWARD GREY: Fly-Fishing.
