Living without an aim is like sailing without compass. If there is no aim, we will get lose. Last term, I couldn't accept the truth which I failed in my math examination. I decided to give it up, so I skipped from classes frequently. Considered my case, my teacher offered me several detailed approach and advised me to set a short-term goal to improve my math. Finally, I work harder than ever and made great progress in her math. In my opinion, success lies in a series of goals. However, we should remember to make our targets clearly and try our best to realize our dreams.
