A man can stand a lot as long as he can stand himself. He can live without hope, without friends, without books, even without music, as long as he can listen to his own thoughts.

To become a good dog-doctor it is necessary to love dogs, but it is also necessary to understand them - the same as with us, with the difference that it is easier to understand a dog than a man and easier to love him.
