Every stage of life has its troubles, and no man is content with his own age.
Be not arrogant when fortune smiles, or dejected when she frowns.
If lucky be not proud; if unlucky, do not despond.
Let the blacksmith wear the chains he has himself made.
He who does not know how to be silent will not know how to speak.
Begin: To have commenced is half the deed. Half yet remains; Begin again on this and thou wilt finish all.
