Success consists in being successful, not in having potential for success. Any wide piece of ground is the potential site of a palace, but there's no palace till it's built.
Fernando PessoaThere's a tiredness of abstract inteligence, and it's the most horrible of tirednesses. It doesn't weight on you like the tiredness of the body, nor does it worry you like the tiredness of knowledge and emotion. It's a weightiness of the conscience of the world, an inability of the soul to breathe.
Fernando Pessoa
