【英文原文】
To pursue joy is to lose it.
The only way to get it is to follow steadily the path of duty, without thinking of joy, and then, like sheep, it comes most surely, unsought.
What sunshine is to flowers, smiles are to humanity.
They are trifles, to be sure, but scattered along life's pathway, the good they do is inconceivable.
Happy people roll with the punches.
They know from experience that everything changes.
Today's good fortune may vanish tomorrow -
today's crises may turn out to be tomorrow' s good fortune.
When we think about happiness, we usually think of something extraordinary, a pinnacle of sheer delight.
And those pinnacles seem to get the rarer, the older we get.
