The slow overcomes the fast.
The weak overcomes the strong."

"Тhe gentle overcomes the rigid. The slow overcomes the fast. The weak overcomes the strong." … "Everyone knows that the yielding overcomes the stiff, and the soft overcomes the hard. Yet no one applies this knowledge."
老子 Lǎozi (c. 6th – 5th century BC) was a Chinese monist philosopher; also called Lao Zi, Lao Tzu, Lao Tse, or Lao Tze. The Tao Te Ching (道德經, Pinyin: Dào Dé Jīng, or Dao De Jing) represents the sole document generally attributed to Laozi.
The flexible are preserved unbroken. The bent become straight. The empty are filled. The exhausted become renewed. The poor are enriched. The rich are confounded. Therefore the sage embraces the one. Because he doesn't display himself, people can see his light. Because he has nothing to prove, people can trust his words. Because he doesn't know who he is, people recognize themselves in him. Because he has no goal in mind, everything he does succeeds. The old saying that the flexible are preserved unbroken is surely right! If you have truely attained wholeness, everything will flock to you.
To realize that you do not understand is a virtue; not to realize that you do not understand is a defect.
