President David O. McKay, in the October 1968 general conference, spoke about several traits that characterize a successful leader or teacher in the Church: 1. “ Implicit faith in the gospel of Jesus Christ as the light of the world, and a sincere desire to serve him. This condition of the soul will make for companionship and guidance of the Holy Ghost.” 2. “ Unfeigned love for the … members, guided by determination to deal justly and impartially with every member of the Church. Honor the … member, and the … member will honor you.” 3. “ Thorough preparation . The successful leader knows his [or her] duties and responsibilities and also the members under his [or her] direction.” 4. “ Cheerfulness —not forced but natural cheerfulness, springing spontaneously from a hopeful soul” (in Conference Report, Oct. 1968, 144).
