There is an optimism which nobly anticipates the eventual triumph of great moral laws, and there is an optimism which cheerfully tolerates unworthiness.
The most common cause of low prices is pessimism - some times pervasive, some times specific to a company or industry. We want to do business in such an environment, not because we like pessimism but because we like the prices it produces. It's optimism that is the enemy of the rational buyer.
But the nearer the dawn the darker the night, And by going wrong all things come right. Things have been mended that were worse, and the the worse, the nearer they are to mend.
We should cultivate the optimistic temperament, and endeavour to see the good that dwells in everything. If we sit down and lament over the imperfection of our bodies and our minds, we profit nothing; it is the heroic endeavour to subdue adverse circumstances that carries our spirit upward.
We look for some reward of our endeavors and are disappointed that not success, not happiness, not even peace of conscience, crowns our ineffectual efforts to do well. Our frailties are invincible, our virtues barren; the battle goes sore against us to the going down of the sun.
