Reflection
Begin by treating a boundary like a sketch: a quick, low-stakes outline of where you need space and why. Think in plain, specific terms—who, when, and what you will do differently—so it stays useful rather than emotional.
Use tiny experiments to test the lines you draw. Phrase a boundary as a short sentence you can repeat; try it in one low-cost situation, notice how it feels, and adjust the wording rather than abandoning the idea.
Over time a sketch becomes a reliable map for your days. Keep the tone practical and kind to yourself: boundaries are tools for clearer rhythm, not weapons or perfection tests.
