As teenagers， you have a lot of 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 top ten students in your class.

Once you find a dream， what do you do with it? Do you ever try your best to make your dream real? Making our dreams real is life’s biggest challenge.

You may think you’re not very good at some subjects， or that it is impossible for you to become a writer. These kinds of thoughts prevent you from being successful.

In fact， everyone can make his dream come true. The first thing you must do is to remember the dream in your mind. 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 is made up of small ones. Please never give them up.

You may have difficulties on the way to your dreams. But the biggest comes from you 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 an ice cream 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 interests.
