The man of wisdom is never of two minds; the man of benevolence never worries; the man of courage is never afraid.
Therefore the superior man is watchful over himself, when he is alone.
All things are already complete in oneself.
Don't worry if people don't recognize your merits; worry that you may not recognize theirs.
The end of the day is near when small men make long shadows.
Isn't it a pleasure to study and practice what you have learned?
