Nothing is impossible

‘Nothing is impossible’, I heard someone say.
I really doubt this statement, by the way.
We can’t fly like a bird, can we?
Or we can’t swim like a fish in the sea.

We can’t move faster than a cheetah.
We can’t just go to stars.
We can’t be rich in a minute.
Someone even can’t read or write in English.

So is ‘nothing is impossible’ really true?
Asking my friend is what I do.
He said, no it’s not. Its truth is not even near.
Nothing is really possible since he has been doing ‘nothing’ for years.
