Be not too confident

"Be not too confident in thine own opinion, but be ready also gladly to hear the opinions of others. Though thine own opinion be good, yet if for the love of God thou foregoest it, and followest that of another, thou shalt the more profit thereby. For I have often heard that it is safer to hear and to receive counsel than to give it. It may also come to pass that each opinion may be good; but to refuse to acquiesce with others when reason or occasion requireth it, is a mark of pride or wilfulness." From Thomas à Kempis' 15th century devotional book, "The Imitation of Christ" (Book I, Chapter IX, "Of Obedience and Subjection"). From William Benham's 1886 translation.
