杞人憂天?

老頭在電話中很樂觀， 聲音仍然是那麽嘹亮， 充滿活力， 哪裏象個病人？

或謂: 少年不識愁滋味, 為賦新詞強說愁?

又或謂: 塞翁若無愁半點, 緣何少年心獨憂?

With that said, no one should underestimate the importance of planning for the unexpected, financially and psychologically. 

And, when it comes to priority, it should always be: oneself first, family second, and work last, for the simple reason that one cannot take care of family, let alone work, without taking care of him/herself first.
