I remember once upon a time, when I was running 800meters, I felt there seemed to be the impossible mission for me, I wanted to give up, then my teacher told me that I should not think about the 800meters, I should set up 100meters for myself, then I wouldn’t be so tired. I did as he told me, indeed, every time when I finished the small goal, I was happy, in the end, I finished the running. I learn the lesson that we need to set up the best goal, it means we can make the small goals, which are so easy for us to realize. Then every time we finish the small goal, we will close to our final destination.
