Look before you leap. 三思而后行。

Pride goes before a fall. 骄必败。

The golden ape is before us. 前途无限美好。

Your life is still before you. 来日方长。

Our services are before you. 我们乐于为你服务。

One must sow before one can reap. 先有播种后有收获。

Cast pearls before swine. 明珠暗投。

Put the cart before the horse. 本末倒置，前后颠倒。

Don’t count your/the chickens before they are hatched. 鸡蛋未孵，勿先数雏；不要高兴得太早。
