阅读短文，根据要求完成下面各小题。
As teenagers, you have many dreams. 3These dreams can be very big, such as winning the Nobel Prize, or they can be very 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 Mattews tells us that making our dreams come true is the biggest challenge in life.
“You may think that 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 realizing your dream,” the book says.
Don’t let it leave your heart. Keep telling yourself what you want. Do this step by step and your dream will come true faster because a big dream, in fact, is made up of many small dreams.
You must also never give up your dream.4There will be difficulties on the way to your dream. But the biggest difficulty comes from yourself. You need to decide what is the most important. Studying instead of watching TV will lead to better exam results, while saving five yuan instead of buying a toy means you can buy a new book.
As you get closer to your dream, it may change a little. This is good as you have the chance to learn more skills and find new interest.
