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

Luck runs out but safety is good for life. – Author unknown

To keep oneself safe does not mean to bury oneself. – Seneca (Seneca the Elder)

It is as much your duty to be careful and comply with safety rules as it is to properly perform your work. – Safety saying, circa early 1900s
