Do not depend on others for safety — Help yourself. – Safety saying, circa early 1900s

Do not assume that she who seeks to comfort you now, lives untroubled among the simple and quiet words that sometimes do you good. Her life may also have much sadness and difficulty, that remains far beyond yours. Were it otherwise, she would never have been able to find these words. – Rainer Maria Rilke

Our insignificance is often the cause of our safety. – Aesop

Safety brings first aid to the uninjured. – F.S. Hughes, c.1912
