History demonstrates that participants in financial markets are susceptible to waves of optimism. Excessive optimism shows the seeds of its own reversal in the form of imbalances that tend to grow over time.
There is an optimism which nobly anticipates the eventual triumph of great moral laws, and there is an optimism which cheerfully tolerates unworthiness.
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.
