根据短文内容，选择最佳答案。  As teenagers, you have many dreams. These dreams can be very big, such as winning the Nobel Prize, or they can be small. You may just want to become one of the ten best students in your class. Once you find a dream, what do you do with it? Do you ever try to make your dream real? Follow Your Heart by Australian writer Andrew Matthews tells us that making our dreams real is life’s biggest challenge. You may think you’re not very good at some school subjects, or that it is impossible for you to become a writer. These kinds of thoughts stop you from getting your dream, the book says.
