Between two stools one falls to the ground.腳踏兩頭要落空。

Beware beginnings.慎始為上。

Big mouthfuls ofter choke.貪多嚼不爛。

Bind the sack before it be full.做事應適可而止。

Birds of a feather flock together.物以類聚，人以群分。

Business is business.公事公辦。

By doing we learn.經一事，長一智。

Jack of all trades and master of none.門門精通，樣樣稀松。

Judge not from appearances.人不可貌相，海不可斗量。

Justice has long arms.天網恢恢，疏而不漏。

Keep good men company and you shall be of the number.近朱者赤,寫作指導，近墨者黑。

Kill two birds with one stone.一箭雙雕。
