You wear a smile on your face

 

脸上带着微笑

 

Life is a topsy-turvy event.

 

It doesn't matter how hard scientists/researchers try to predict it, it remains unpredictable.

 

You plan for today in the morning, and by the afternoon you have to modify it to accommodate something unplanned.

 

Whatever the situation may be, wearing a smile has a positive impact on your body and mind.

 

So, if you are being found mostly with a smile, you should consider this as a sign of getting matured.
