Everyone's a Wannabe Until They Be
Hey, it might not look like correct English but it makes sense. Plus this garbled grammer is able to communicate even more than a proper version of this statement.
The first definition of the word be is to become. The truth is that everyone started as a wannabe on the outside looking in. Regardless of any other advantage, to get where they are every single successful person has had to stand up and put in the effor to become what they are.
A second definition of the word be is to be present. This is more on an existential and spiritual level but I think it's equally important as becoming. Because without this second kind of be, the first kind will never be enough.
