Cura te ipsum
From Self-sufficiency
Cura te ipsum ("Take care of your own self!") is a Latin injunction, urging physicians to care for and heal themselves first, before dealing with patients.
Cura te ipsum was made famous in the Latin translation of the Bible, the Vulgate. The proverb was quoted by Jesus, as recorded in the Gospel of Luke chapter 4:23. Luke the Evangelist was himself a physician.
