The much droplets

The much droplets of water
Forms a big lake
The lake beside a lake
Makes a great flow
It will smash ,it will take
Every thin opinions its flow
As it may pass  ,or may go
The ant beside the ant
Formed a big armed
They formed a big nation
They can't surrender or frustrate
They attack every thing
They can destroy high building
In hours, to spread ruin
The minutes beside the minutes
Formed hours and days
Calculated how hours
Do you loose in days
Your age is minutes
Your age is so worthy
Don't loose it so easy?
