我一直在想，為什麽中國的孩子們在上大學以前顯得尤為突出，之後舉步維艱, 我從學校接我九歲的兒子時我跟他討論這個話題時，他給我介紹一個新的概念--街頭智慧, 它通常不會記載在書裏，也很難在任何一堂課裏學到, 是平時經驗積累的知識

To be street smart means you have situation awareness.  You can assess the environment you are in, who is in it, and what the available angles are. Being on the street, or in the trenches, or whatever low to the ground metaphor you prefer, requires you learn to trust your own judgment about people and what matters. This skill, regardless of where you develop it, is of great value everywhere in life regardless of how far from the streets you are.
