That's a lovely poem. To me, it's saying that if you are fortunate enough to meet that special person who can make your life complete, everything that came before fades into insignificance. It doesn't matter so much anymore, because from that time on it is a new beginning- waiting for new footprints in the pristine snow marking the journey of your future life.
It could also mean a new 'rebirth' after some special revelation or insight you may have had- causing you to start afresh. Whatever you had in mind, yourself, when you wrote it, its a good thought provoking poem
