"When events run a little against your desires,
Direct your thoughts to those who are not as well off.
Then resentment and blame will of themselves disappear.
When your mind becomes a bit slovenly,
Direct your thoughts to those who have excelled beyond your own lot.
Then your spirits will of themselves be restored."
Master of the Three Ways Reflections of a Chinese Sage on Living a Satisfying Life
Hung Ying-ming on when your mind becomes a bit slovenly.
