There once lived a young man who was always unhappy and complained about his poverty. One day, he went to see a fortune teller to inquire how to become      16    . The fortune teller said, "Young man, you are already wealthy now."
"Where is my wealth?" the young man asked     17   .
"It is with you. Your     18    is (are) your wealth. You use them to see this world. You use them to see all the     19   things in this world. You can read, study and learn. Your hands are your wealth. You can use them to work. You can use them to hug your beloved ones. Your     20    are your wealth. You can go to any places..." the fortune teller said.
"You call these wealth? Everyone has them," the young man said.
"These are wealth. What you have now are not what others can luckily have. Are you     21    to give your eyes to me? I am willing to give you a lot of money to     22     for them," the fortune teller said.
"No, are you crazy? I am not going to exchange my eyes for money! They are     23    to me!" the young man     24    .
"Precisely, these are wealth to you. You will not exchange them for money. Furthermore, although a lot of people have their wealthy things, they do not     25    them or treasure them. They are not     26    to Heaven for giving them their wealth. They even complain that Heaven is unfair to them. Do you want to    27    one of them before you will treasure them?" the fortune teller said.
Everyone is wealthy. But we should not     28   it for granted. We need to treasure our wealth, take care of it and use it     29    . We should not overuse it because once it is     30    , it is gone forever. Remember it is our wealth that we do not want to lose.
