What do you need to know before it's too late.

 

应该尽早懂得的人生道理

 

A person's actions speak the truth.

 

行为见人心

 

You're going to come across people in your life who will say all the right words at all the right times; but in the end, it's always their actions you should judge them by.

 

So pay attention to what people do. Their actions will tell you everything you need to know.
