"We are not born winners. We are not born losers. We are born choosers."
I've recently seen this attributed to Rav Avigdor Miller. Now, I am not an expert on Rav Miller, but I've read some of his
writings and heard some of his lectures, and this does not sound to me like something that would have come from him.
Google has some results for it, as well as for a couple of forms in the singular - “You are not born a winner. [etc.]",
"You were not born a winner or a loser. [etc.]", and none that I saw were from anyone Jewish-sounding (except when
adding Rav Miller's name to the search).
If anyone can show a source for this coming from Rav Miller, they're welcome to do so.
