Is there such depravity in man as that he should injure another without benefit to himself? - Samuel Johnson

Every man is rich or poor according to the proportion between his desires and his enjoyments; any enlargement of wishes is therefore equally destructive to happiness with the diminution of possession, and he that teaches another to long for what he never shall obtain is no less an enemy to his quiet than if he had robbed him of part of his patrimony.

To a poet nothing can be useless.

Your work is both good and original but the part which is original is not good and the part which is good is not original!
