Don't worry if people don't recognize your merits; worry that you may not recognize theirs.
Study the past, if you would divine the future.
First there must be order and harmony within your own mind.
If you think in terms of a year, plant a seed; if in terms of ten years, plant trees; if in terms of 100 years, teach the people.
It is better to light one small candle of gratitude than to curse the darkness.
One joy dispels a hundred cares.
