最佳的目标 The Best Goal

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. 
我记得有一次，当我跑800米的时候，我觉得这对于我来说是不可能的任务，我想要放弃，然后我的老师告诉我不应该想着800米，我应该为自己定下100米的目标，这样才不会那么累。我按他说的去做，每次我完成了小目标，我就很开心，最后，我完成了跑步。我学到了东西，我们需要定下最佳的目标，这意味着我们可以定下小目标，对我们来说容易实现。每次我完成了小目标，就会离最终的目的地近了一步。
