There is no constant faith in words and no constant chastity in deeds. They only care about the interests and do everything. If so, they can be called villains - Xunzi

What you say must be done, and what you do must be fruitful.

Skills come from diligence but waste from play; success comes from thinking but failure comes from following.

——Han Yu

A day of hard work can lead to a good night's sleep; A life of hard work will lead to a happy sleep

——Leonardo Da Vinci (Italy)
