• I've always loved running. When I was young, I used to run everywhere. I ran at school, and I joined a running club when I was 12. I'm 23 now, and I still love it. In fact, I'm a professional runner. But I've had some difficult times.
• When I was 18, I got very sick with a virus. My doctor told me I couldn't run for six months. It was the worst thing that could have happened to me. Running was my life. I didn't know what to do without it. But then I started thinking about how much I loved it and how much I wanted to run again. After six months, I started running slowly, and then I started training again. It was really hard at first, but I did it. And I think it made me stronger.
• The next year, I won my first big race. I felt amazing. I thought nothing could stop me. But then in 2012, I went to the Olympics in London and I didn't win. I came second. It was so disappointing. I felt like a failure. But then I thought about all the work I'd done, and how far I'd come. I decided not to give up. I trained harder than ever. And in 2013, I broke the world record for the women's 800m. It was an incredible feeling.
• In 2014, I got injured. I couldn't run for a whole year. It was really difficult. But I didn't want to give up, so I worked hard to get better. The next year, I came back and I won my first race. It was such a good feeling. And last year, I won another gold medal in the Olympics. I'm so proud of myself. I never gave up, even when things were really hard.
• I think the most important thing is to believe in yourself. And never give up, no matter what happens.
