We all juggle many responsibilities, in multiple areas of life at the same time: house chores, kids activities, work responsibilities, zoom meetings, doctor's appointments, errands, etc. etc.
Now, think of all the responsibilities that you juggle as balls, but made from different materials: some are rubber and will bounce, some are plastic and will drop and roll away, some are glass and will break when dropped, some are heavy and make a crash when they come down.
