James Boswell, Journal of a Tour to the Hebrides
(Tuesday, 14th September):
I expressed some surprize at Cadogan's recommending good humour, as if it were quite in our power to attain it. -- Johnson. "Why, sir, a man grows better humoured as he grows older. He improves by experience. When young, he thinks himself of great consequence, and every thing of importance. As he advances in life, he learns to think himself of no consequence, and little things of little importance; and so he becomes more patient, and better pleased. All good humour and complaisance are acquired."
