Remember not to blame feelings on others. Happiness is a choice so choose to be happy! Surround yourself with people who choose to be happy not because someone is making them happy or because things are going their way; that is not true happiness.
The hearth and the Salamander can also mean happiness and if Montag chose to be happy or not. The two things in his life his home and his work. Did it really make him happy. He chose happiness over this home and his work by reading the books.
