In general, all the same formatting and content rules apply here, except that you must summarize everything so that it fits onto a single page.  You may go to two pages if you have had a long career.  A résumé is meant to have immediate impact, with no turning of the pages.  All the necessary information is in one place at one moment.  Think of this as a snapshot, rather than a movie.

· ADVICE. Of course it's hard.  But it's only hard.  And yes, it can't possibly capture everything you do, and how you're changing, and what your potential is.  There, there.  Now get to it, and keep it current.  You will likely use this document much more than your vita.  And you may as well do this at the same time, with all your information in front of you.

"Put all your eggs in one basket, and--watch that basket."

"Life.  It's full of such sadness and sorrow, sometimes I think it's better not to be born at all!  But how many people do you meet in a lifetime who were that lucky?"--Yiddish saying

You don't need to include references on a résumé.  You may want to say something like "References Available Upon Request" at the end, especially if you have the room.
