Fear not for the future, weep not for the past - Percy Bysshe Shelley

Poetry is not like reasoning, a power to be exerted according to the determination of the will. A man cannot say, 'I will compose poetry.' The greatest poet even cannot say it; for the mind in creation is as a fading coal, which some invisible influence, like an inconstant wind, awakens to transitory brightness; this power arises from within, like the colour of a flower which fades and changes as it is developed, and the conscious portions of our natures are unprophetic either of its approach or its departure. Could this influence be durable in its original purity and force, it is impossible to predict the greatness of the results; but when composition begins, inspiration is already on the decline, and the most glorious poetry that has ever been communicated to the world is probably a feeble shadow of the original conceptions of the poet.

Hence in solitude, or that deserted state when we are surrounded by human beings and yet they sympathize not with us, we love the flowers, the grass, the waters, and the sky. In the motion of the very leaves of spring, in the blue air, there is then found a secret correspondence with our heart.
