The mind should have someone whom it can respect - Seneca
Quote
The mind should have someone whom it can respect—someone whose authority might make even its inner shrine more hallowed. . . . Happy is he who can so respect a man that the very memory of that man can calm and direct him! He who can thus respect another will quickly be respected himself. Therefore, choose a Cato, or if thisseems too strict for you, choose a gentler spirit—a man like Laelius. Choose someone whose life and speech pleases you, and who displays outwardly the same character he has. Present him to yourself always as your guardian or exemplar. There is need, I insist, for someone against whom to measure our way of life; unless you have a ruler, you can’t straighten what is crooked.[
