Reworded so that it wasn't a direct quote (otherwise I'd have given credit), but yes: his words were the exact inspiration for this meme.
That whole "Anything is possible!" bit is SO overused by the masses who refuse to think for themselves about...well, most things. When I came across that quote of his that I took down a year ago, I could not believe it!
I HAD to do something with it.
Like I said, if it was an exact quote, credit would have unquestionably been given.
