Where and Who of "Congradulations, You have chosen the most difficult business business in existence!"

[John Bowles <johnbowles@xxxxxxxxxxxx>]

In either the John Hayden book "The 21 Irrefutable Truths of Trading" or 
one of the Mark Douglas books I remember reading a great sentence 
"Congradulations, You have chosen the most difficult business business 
in existence!" or something very close to that. I don't suppose anyone 
knows exactly where this is (including the book and page number). I want 
to frame it.
Thanks,
John.
