"The sky is not the limit"

It seems that the sky is not the limit
Is the sea the limit ?
Is the earth the limit ?
Is the the sky the limit ?
Where is the limit ?

Limit !
What is a limit ?
Where is a limit ?
Why is a limit ?

If the sky is not the limit
What should be the limit ?
Do we need a limit ?
Should it be a limit ?

Look at this duck
Do you think that it knows about ?
Sure,
While diving, it realises there is a limit
The limit is where it puts it
What about you ???
