And when we begin, there is no end

We begin to respire much before our lungs are formed.
We begin to digest much before our guts are formed.
We begin to think much before our thoughts are formed.
We are born much before we are fully born.
Tadpoles begin to swim the moment  they are born.
We are not tadpoles.
We begin when we are ready to begin.

And when we begin, there is no end.
