Now listen to the following recording and answer questions 23 to 25.
    My name is Nick Vujicic. I was born in Australia in 1982, and moved from Australia to California in the year 2006. You know, people always ask me, " What happened to you and how did you overcome what you’ve been through?"(23)The title of the message that I’ve been given is "Transforming the walls into doors". When I speak corporately, the line that I like to use is "Changing obstacles into opportunities".
    Now, I am very well aware to share with you as well. I know that there are a billion people going hungry today. I know that this year a million people will commit suicide. That is one every second. We’re all looking for something. We’re all looking for hope. Hope you can’t just have because you were born with hope. No, we’re born with pain. We’re born and live through difficulties.
     (24)In our life — my parents always taught me that even though we don’t know why we were born this way, we have a choice. If my parents never told me that I was beautiful the way I was, and if my parents never told me that I was special and that I was loved, I wouldn’t be here today. And when you try to tell your children that they’re beautiful, they say, "Of course I’m beautiful. I’m your son, your daughter: of course you’re going to say that. " But they’re right. Every single human being has value and my value is not determined on how I look or what job I have, or where I’m from, where I was born and how much money I earn. All that stuff is nothing.
    I want to ask you today, if I gave you a billion dollars, would you be happy? Then if your mom died tonight, would you be happy? No. Because money is something that cannot heal the soul. So many teenagers are looking for love. Love does heal the soul and love does complete the soul.
     (25)Sure, I didn’t get a miracle. But I realized something. If God doesn’t change my circumstance, he’s going to use my life to be a miracle for someone else. When you don’t get a miracle, you can still be a miracle for someone else. I am not a superhero, I go through ups and downs, so do you. For me, I want you to know that’s how I’ve overcome.
