Everything has period,

The moon waning to full.

The sun up to down.

Through that,

We can see more things.

The season has its period.

From spring to summer, 

From autumn to winter.

And more,

The day is from daytime to night.

  And the most important,

We always feel that,

Sometimes you are full of energy,

And another time you are so tired all day.

So,

You should know the period.

And you should follow the period.

Then you will feel good.

Now I'm doing this.

Sometimes I want to update my English article,

Then I do it.

But sometimes i AM tired,  All I have other things.

So I didn't update it.

But there's not a work,

So I feel all good.

That's all.

thank you very much
