I had a very special teacher many years ago whose husband died suddenly of a heart attack. About a week after his  36 , she shared her insights(顿悟) with the students. When the class was nearly over, she  37  and said, “I would like to  38  with all of you a thought that has  39  to do with class, but which I feel is very  40 .

“Each of us is put here on the  41  to learn, share, love and appreciate ourselves. None of us knows when this  42  will end. At any moment it can be  43 . Perhaps this is life’s way of telling us that we must make good  44  of every day.” Her eyes beginning to  45 ,she went on saying, “So I would like you all to  46  me.

For as we get older, it is not the things we did that we often regret,  55  the things we didn’t do.
