Where's my goal

My Chinese friend told me she spent a whole year on preparing for her applyapplication to an Australian college, and during that time, she needed to get up at 7:00 and go to study in the library everyday. She used to be a lazy student, but now she has fulfilled her dream. I wonder how could she did that it. She said it was because she had a dream which is deserved to fighting for. I wonder that when will whether I'll ever have a dream and make me strong enough to push me into being a the hard-working person that I used be.
