"Let's get the ball rolling on this proposal."
"Who wants to get the ball rolling with introductions?"

The image: A ball at rest requires effort to start moving, but once rolling, it continues with its own momentum. Getting the ball rolling implies that starting is the hardest part.

What it implies: The person saying it is ready to begin, or is encouraging others to start. It has a slightly energetic, motivational quality.
