Praise makes good men better, and bad men worse. 好人越誇越好，壞人越誇越糟。

Praise is not pudding. 恭維話不能當飯吃。

Practice makes perfect. 熟能生巧。

Pour water into a sieve. 竹籃子打水一場空。

Pleasure comes through toil. 苦盡甘來。

Please the eye and plague the heart. 貪圖一時快活，必然留下隱禍。

Plain dealing is praised more than practiced. 正大光明者，說到的多，做到的少。

Penny wise, pound foolish. 貪小便宜吃大虧。

Patience is the best remedy. 忍耐是良藥。

Out of sight, out of mind. 眼不見，心為靜。
