It is a time when one's spirit is subdued and sad, one knows not why; when the past seems a storm-swept desolation, life a vanity and a burden, and the future but a way to death.
Mark TwainEvolution is the law of policies: Darwin said it, Socrates endorsed it, Cuvier proved it and established it for all time in his paper on The Survival of the Fittest. These are illustrious names, this is a mighty doctrine: nothing can ever remove it from its firm base, nothing dissolve it, but evolution.
Mark TwainSuccess is a journey, not a destination. It requires constant effort, vigilance and reevaluation.
