Courage is required to make an initial thrust toward one's coveted goal, but even greater courage is called for when one stumbles and must make a second effort to achieve. Have the determination to make the effort, the single-mindedne ss to work toward a worthy goal, and the courage not only to face the challenges that inevitably come but also to make a second effort, should such be required.

— Thomas S. Monson
