The problem is not always poor productivity.

Sometimes you simply have too much on your plate.

Too many commitments. Too many favors. Too many unfinished obligations. Too many things you agreed to before considering what they would actually cost.

The Capacity Rule is a practical, research-informed guide to managing commitments before they overwhelm your calendar, attention, energy, and recovery.

Instead of teaching you how to squeeze more work into an overloaded life, this book helps you decide what deserves to enter your life in the first place—and what needs to change when your current commitments no longer fit.

Inside, you will learn how to:

• Separate capability from real capacity.
• Identify the hidden cost of a “small” yes.
• Build a realistic capacity baseline.
• Evaluate new requests before accepting them.
• Use the Capacity Rule to decide what fits.
• Create time to think before answering under pressure.
• Renegotiate scope, timing, frequency, ownership, and expectations.
• Decide what to keep, reduce, delegate, delay, or remove.
• Protect open space before it gets consumed.
• Run a short weekly capacity review that catches overload early.

This is not a book about becoming less dependable. It is about becoming more deliberate.

A new commitment does not create new capacity. If something comes in, something else must fit, move, shrink, or leave.

The goal is not to carry more.

It is to decide what deserves to be carried.
