It’s important to know our goodness and badness because it can help us to  improve ourselves better. Therefore, we should know ourselves as much as we can.  I think I have three main merits. They are filial piety, honest and hardworking.  Filial piety and honesty are the two basic qualities that people should have.  And working hard can help to get knowledge and improve myself. However, no one  is perfect. I have some week points, too. For example, I never make plans for my  life and study. As a result, sometimes I am a little laziness because I don’t  have tasks that must be finished. I hope I can change and be better.
