Why do scheduling, billing, and phones all hit me at once?

You call it overwhelm, as if it were a single wave. Look again. Scheduling is one task. Billing is another. Phones are a third. They only feel like one crushing mass because you have let them sit together, unsorted, unsized, unnamed. This is not a measure of your strength. A man can carry three light loads easily and one heavy, tangled load with great difficulty — even if the weight is the same. You have been carrying the tangle. No wonder your arms shake. What is in your power right now is small and exact: separate the three things. Decide which is smallest. Do that one. The rest can wait its turn — it was never asking to be done all at once. You imposed that part yourself.
