To choose , to give up 为题的演讲稿   The  Secret  of  Happiness     A  young  man  once  came  to  meet  me Jeruslem . He  had unusually  happy disposition , so  I  asked  him  what's  his  secret .He told  me ,"When I  was 11  years  old , I  rexeived  a  gift  of  happiness  from  God ."     "I  was  riding  my  hicyele  when  a  strong  gust  of  wind  blew  me  onto  the  ground  into  the  path  of  an  oncoming  truck . The truck  ran  over  me and  cut  off  my  leg."     "As  I  lay  there  bleeding . I realized  that  I  might  have  to  live  the  rest  of  my  life  without  a  leg .  How  depressing !  But then  I  realied  that  being  depressed  won't  get  my  leg  back . So  I   decided  right  then   and  there  not  to  waste  my  life  despairing ."     "When  my  parents  arrived  at  the  hospital   they were  shocked  and  grieving . So  I  told   them  ,'I  have  aleady  adapted . Now you  alos  have  to  get  used  to  this .'  "     "Ever  since   then  ,when  I  see  my  friends  getting  upset  over  litte  thing:  their  bus  came  late  ,   they  got  a  bad   grade  on  a  test, somebody  msulted   them,I  still  just  enjoy  life  ."     At  age  11 ,  this  young  man  attamed   the  clarity  that  it  is  a   waste  of   enenrgy   to  focus  on   what   you   have   missed , and    that the  key    to   happiness   to   take   pleasure   in    what   you  have .We've always been told it's true, but now experts have proved that money really can't buy you happiness. They quizzed jackpot winners and came up with 10 tips to keep you feeling on top of the world. And the results were surprising. No flash cars of expensive jewellery. Instead it was the simple pleasures, available to almost anybody, that bring the most enjoyment. Top of the list is spending time with your family. But jackpot winners' advice is: "Don't give up work. Having a regular routine and social interaction are essential. Keeping up friendships is important too, as is a stable marriage. Buying your own home, preferably in the North where people are friendlier, is a good idea. But don't get into debt.
