Ellen G. White’s quote on Contentment:

E G White, Child Guidance, p.359:
“This essential lesson of CONTENTED industry in the necessary duties of life, however humble, is yet to be learned by the greater portion of Christ’s followers. If there is no human eye to criticize our work, nor voice to praise or blame, it should be done just as well as if the Infinite One Himself were personally to inspect it. We should be as faithful in the minor details of our business as we would in the larger affairs of life.”

E G White, Prophets and Kings, p.219:
“Success depends not so much on talent as on energy and willingness. It is not the possession of splendid talents that enables us to render acceptable service; but the conscientious performance of daily duties, the CONTENTED spirit, the unaffected, sincere interest in the welfare of others. In the humblest lot true excellence may be found. The commonest tasks, wrought with loving faithfulness, are beautiful in God’s sight.”

E G White, Adventist Home, p.154:
“But whether the home be humble or elegant, its appointments costly or the reverse, there will be no happiness within its walls unless the spirit of its inmates is in harmony with the divine will. CONTENTMENT should reign within the household.”
