Sigma is the initial letter of the Greek word SPOUDE (spoo-day), which means earnestness.
Earnestness is enthusiasm measured by achievement, disciplined by reason and ennobled by sincerity. It is that dynamic quality which is essential for all great achievement.
Earnest people reject both temerity and timidity. They have courage to match their convictions. They inspire confidence, invite action, and generate progress.
Without Earnestness, both Honor and Wisdom lose much of their potential effectiveness. Noble purposes, defined with wisdom and upheld with honor, remain evanescent dreams without the driving power of sensible enthusiasm. The greatest personal achievements are tributes to the blending of honor, wisdom and earnestness in the minds and hearts of those who lead. Rewards for individual and progress for society surely proceed from this wholesome union of qualities.
To each of you, much has been given in mind and body and spirit. Of each of you, accordingly, much is expected. Earnestness will help provide the perseverance that dispels weariness, the forward thrust that overcomes opposition and the resilience that rebounds from reverses. To the earnest person, problems become opportunities for service and profit.
I ask you to accept Earnestness as a guide and stimulant in your personal conduct of every day of your life.
