"I am surprised at three things: 1. [A] man runs from death while death is inevitable. 2. One sees minor faults in others, yet overlooks his own major faults. 3. When there is any defect to one’s cattle he tries to cure it, but does not cure his own defects."
Umar Ibn Al-Khattab (Radiallahu anhu)
Reminds me of the Tolstoy quote: “Everyone thinks of changing the world. No one thinks of changing himself.” Worth some consideration.
