Confidence in yourself is the first step on the road to success.
自信是成功的第一步。
Constant dripping wears away a stone.
滴水穿石。
Content is better than riches.
知足常乐。
Count one's chickens before they are hatched.
高兴得太早了。
Courtesy on one side lasts not long.
来而不往非礼也。
以牙还牙,以眼还眼。
An eye for an eye and a tooth for a tooth.
