I have this cassette by Tony Robbins, on which he’s selling one of his
seminars. At one point he says:

"There is a major Fortune 500 corporation, and the man who is the CEO
of that company is a gentleman who started out dirt poor, without the
education, without the background, and now he’s running one of the
most successful companies on Earth. We’re going to find out what
exactly his core beliefs are."

Who is this man, and what are those core beliefs?

It is only a bet, but being a Holocaust child, George Soros did not
exactly had a happy camper childhood, and his business philosophy is
very interesting (though not what I'd expect Tony Robbins to put as an
example).

There are many such Horatio Alger stories. Check out the Horatio Alger
Foundation's Web site at www.horatioalger.com.

I don't know if Wendy's is in the Fortune 500, but the late Dave
Thomas was a high school dropout.

Gotta be Sam Walton of Walmart.
