To succeed or to be happy?

I'm in Taichung today.  

Like me, my students must be having fun now.   Whether they did well on the UEE or not, it can't be changed.  What can be seized is this and the following moment.  I remember many years ago I heard a lecture made by Mr. Cheng (鄭石岩).  He said what parents should teach their children is not to succeed but to be happy.  On hearing that, I was surprised because most books and speeches taught people how to be a successful person.  I forgot how Mr. Cheng convinced us, but finally I realized why he said so.  Since we cannot control what happens to us, we'd better learn to accept it happily.  This is easy for me to understand, because I always believe that "Man proposes; God disposes."
