Fyodor Dostoyevsky said this quote
“ Why is it that a convict never saves his money? Well, not only is it difficult for him to keep it, but prison life is so miserable that a man, of his very nature, thirsts for freedom of action. His position in society makes him so irregular a being that the idea of swallowing up his capital in orgies, of intoxicating himself with revelry, seems to him quite natural if only he can procure himself one moment's forgetfulness. ”
