Think of a businessperson carrying bags through an airport terminal. She can carry a laptop bag with ease. Roller case too. Maybe a carry-on bag atop the case. All this can be done with dexterity. Effortless.

But one more bag? Two more? Four more bags and two more rolling cases?

Maybe.

But at some point, there will be undue strain. At some point, something will drop.

We can all carry heavy loads. We can take on more roles and responsibility. However, it's possible to reach a point where we don't carry those responsibilities well. It's possible to reach a point where we start dropping things. Worse: we might be carrying so many things that we don't even know when one falls.
