Accustom yourself every morning to look for a moment at the sky and suddenly you will be aware of the air around you, the scent of morning freshness that is bestowed on you between sleep and labor. You will find every day that the gable of every house has its own particular look, its own special lighting. Pay it some heed if you will have for the rest of the day a remnant of satisfaction and a touch of coexistence with nature. Gradually and without effort the eye trains itself to transmit many small delights, to contemplate nature and the city streets, to appreciate the inexhaustible fun of daily life.
