EVERYONE has fears (畏惧) in their hearts sometimes. But what you need to do is overcome (克服) them! US singer Katy Perry, 28, once wrote the song Roar (《咆哮》) to help her feel strong! It shows how Perry stands up and discovers her own power (力量). “Roar is a song about being able to finally speak up for yourself,” Perry told the UK’s Radio 1 DJ Scott Mills. This single was released in August 2013. It became No 1 on the iTunes download chart within 24 hours from when it was released. How powerful is that!
