Ramadan is over! Now what?

What are we supposed to do now that Ramadan is over? Does Ramadan and its blessings/lessons matter after the month has passed? Do we go back now to our old selves and habits? Can Ramadan be part of a greater plan that covers our entire year? Our whole life? This khutbah puts our Ramadan experience in perspective as one part of our ongoing journey towards our Creator.
