I believe that perseverance is vital to success in any endeavor, whether spiritual or temporal, large or small, public or personal. Think seriously of how important perseverance, or the lack of it, has been in your own endeavors, such as Church callings, schooling, or employment. I believe that essentially all significant achievement results largely from perseverance. – Joseph B. Wirthlin, “Never Give Up,” Ensign (CR) November 1987
