When I was in junior high school, I was not a very diligent student. In fact, I was quite lazy. I hated all the subjects that I took during school, especially science. For me science was very difficult. It was hard for me to remember the chemical processes, physics calculations, and biological processes.

    Once, my teacher grounded me in the library because I did not do my Biology homework. The teacher asked me to read several books and make a summary about them. When I was browsing the shelves, I found a book entitled "The inventors of Medicine". I thought "OK, this is a start". I took it out then began reading it.

    I learned from the book about Edward Jenner. He was an English doctor who found the cure for smallpox. The next one was Louis Pasteur. His interest in bacteria led him to discover the treatments for rabies and anthrax. Just like Pasteur, Robert Koch's experiments on bacteria also proved that tuberculosis can be spread to others by contact. Finally, there was Alexander Flemming, a British bacteriologist who found the first antibiotic and penicillin.

    After I read the book, I realised that science is useful for human kind. By studying, we can discover things that can help human kind. Therefore, since that moment, I managed to change my behaviour and became a doctor.
