There'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 PessoaI always live in the present. I donโt know the future and no longer have the past. The former oppresses me as the possibility of everything, the latter as the reality of nothing.
Fernando Pessoa
