Francis Bacon Quote

Men seem neither to understand their riches nor their strength; of the former they believe greater things than they should; of the latter much less. Self-reliance and self-denial will teach a man to drink out of his own cistern, and eat his own sweet bread, and to learn and labor truly to get his living, and carefully to expend the good things committed to his trust.
