“How did you do it, Dad ? How have you   21   not to take a drink for almost 20 years? ”It took me almost 20 years to have the  22  to even ask my father this very  23 question.
When Dad first 24  drinking, the whole family was on pins and needles  25  he got into a situation that, in the past, would have started him drinking again.For a few years we were  26  to bring it up for fear that the drinking would begin again.
“I had this little  27  that I would recite to myself  28  four to five times a day ” was Dad’s  29 to my 18-year-old unasked question.“The  30  were an instant relief and constant reminder to me that things were never so  31  that I could not handle them,”Dad said.And then he  32  the poem with me.The poem’s simple, yet profound (深奥的) words  33  became part of my daily routine as well.
About a month after this talk with my father,I  34  a gift in the mail from a friend of mine. It was a book of affirmations (断言) with one affirmation listed for each  35  of the year.
I 36  opened the book to the page of my birthday to see what words of wisdom this book had in store for me. 37  of disbelief and appreciation rolled down my face.There,on my birthday ,was the  38  poem that had helped my  39 for all these years! It is called The Sereniry Prayer.
God,give me the Serenity(平静)to accept the things I cannot change,the Courage to  40  the things I can,and the Wisdom to know the difference.
