「三人行，必有我师焉」
“When three people walk together, there must be one who can be my teacher”
—— 论语三人行，必有我师焉：择其善者而从之——学习发生在路上，不限课堂。可与有教无类并读。今日：最看不上的同事，也可能是你某项短板的老师。
Among three walking, one is my teacher: follow the good, correct by the rest—learning happens on the road, not only in class. Pair with teaching without class barriers. Today: the colleague you dismiss may teach the skill you lack.
