最佳的目标

I remember once upon a time, when I was running 800 meters, I felt it seemed to be an impossible mission for me, I wanted to give up. My teacher told me that I should not think about the 800 meters, I should set up 100 meters 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.

From my experience, I learn the lesson that we need to set up small goals first. 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。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。

从这段经历中，我明白了我们先要定下小的目标。每次我完成了小目标，就会离最终的目的地近了一步。
