I've learned from experience that the greater part of our happiness or misery depends on our dispositions and not on our circumstances.
The Ballad of M. T. Nutt and His Dog
by Andrew Barton Paterson
The Honourable M. T. Nutt
About the bush did jog.
Till, passing by a settler's hut,
He stopped and bought a dog.
Then started homewards full of hope,
Alas, that hopes should fail!
The dog pulled back and took the rope
Beneath the horse's tail.
The Horse remarked, "I would be soft
Such liberties to stand!"
"Oh dog," he said, "Go up aloft,
Young man, go on the land!"
