In times of change, the learners inherit the earth, while the learned find themselves beautifully equipped to deal with a world that no longer exists.《Steel and Strategy》
孔子说:“有益的朋友有三种,有害的朋友有三种。与正直的人交朋友、与诚实的人交朋友、与见多识广的人交朋友,有益处;与走邪门歪道的人交朋友、与谗媚奉迎的人交朋友、与花言巧语的人交朋友,有害处。”
I don't regret anything I've done.
