A lion does not concern himself with the opinion of sheep.

狮子可不会在意绵羊是怎么想的。

As a sheep, you must run and keep alert.

It is said that soldiers who are fighting togehter often have a strong feeling of brotherhood, so can sheep who eat grass together can unite to combat against a lion?

We turn not older with years, but newer every day.

我们并非在年复一年地变老，而是日复一日地焕然一新。

From Emily Dickinson.

I wish it can be true.

Yesterday I wrote several small samples with Python3.5, their running outputs were nearly the same, and the difference may be the algorithms and the data-structre of them.

Then I found the time complexity of each realization was quite different.

The same is to life.

Our choice will decide whether our life will be easy or not.
