What's left at the end of the effort?

At the end of what you finish, when you're within sight of the finish line, how do you stay engaged at your 100%?

Whether toward the end of a race, a typical work-day, a meeting presentation you're working on, or a large client project...it's very important that the last bit of match the enthusiasm, interest, focus and intention as the steps along the way; going all the way back to the beginning.
