I'm looking for a quote I heard recently at the JFK Library & Museum. 
The film at the beginning of the tour has a segment in which, Edward
R. Murrow asks Senator (I think it was Senator at the time) Kennedy if
there was anything he had read or seen that had really shaped his
life.  JFK then grabs a book from behind him and reads the quote.  I
believe he said it was part of a letter written home by a man named
Allen (Alan) (I don't recall if it was his first or last name).  He
also explains that this man was in the French Foreign Legion during
WWI.  The gist of the quote was that it was more important to him to
feel like he had done what is right, than to be on the winning side. 
I tried asking the Museum staff through email a couple days ago, but
nothing yet...

Hello Zbwaffles,

Here is the quotation.


"Whether I am on the winning or the losing side is not the point with
me. It is being on the side where my sympathies lie that matters.
Success in life means doing that thing then which nothing else
conceivable seems more noble or satisfactory or remunerative. And then
being ready to see it through to the end."

Text of the Orientation Film for the John F. Kennedy Library


Edward R. Murrow: We're going up to Boston to meet Senator John
Kennedy and his bride. Do you have a chance to do much reading?
JFK: Yes, I used to very much, and I try to do it as much as I can now.

Murrow: Have you found anything that has been particularly useful, or
perhaps I could use the word inspirational, to you?

JFK: Well, I do have something here that was written by Alan Seeger
who, as you'll remember, was born in New York and fought in the
Foreign Legion and was killed in the First World War in 916. He wrote
that famous poem, "I Have a Rendezvous with Death." Just before he
died, he wrote a letter home to his mother which I think has good
advice for all of us: "Whether I am on the winning or the losing side
is not the point with me. It is being on the side where my sympathies
lie that matters. Success in life means doing that thing then which
nothing else conceivable seems more noble or satisfactory or
remunerative. And then being ready to see it through to the end."

Good job.  Don't know why I couldn't find that on that site, but
thanks.  Don't spend it all in one place now.
