James Hadfield, fully Captain James Arthur Hadfield

This art of resting the mind and the power of dismissing from it all care and worry is probably one of the secrets of energy in our great men.

It is one of the many paradoxes of psychology that the pursuit of happiness defeats its own purpose. We find happiness only when we do not directly seek it. An analogy will make this clear. In listening to music at a concert, we experience pleasurable feelings only so long as our attention is directed towards the music. But if in order to increase our happiness we give all our attention to our subjective feeling of happiness, it vanishes. Nature contrives to make it impossible for anyone to attain happiness by turning into himself.

It is literally true that in judging others we trumpet abroad our secret faults.
