“Those who know do not speak. Those who speak do not know.”

What does it mean?

People who truly understand something often stay quiet, while those who talk the most often understand the least.

• “A journey of a thousand miles begins with a single step.”– Lao Tzu
• “Knowing others is intelligence; knowing yourself is true wisdom.”– Lao Tzu
• “A leader is best when people barely know that he exists. Of a good leader, who talks little, when his work is done, his aims fulfilled, they will all say, "We did this ourselves."”– Lao Tzu
