Do thematic days work when client emergencies pop up?

Strict time blocking is the fastest way to feel like a failure by Wednesday afternoon. Coding requires getting into a deep mental zone and getting pulled away for a 30-minute marketing task ruins the whole flow.

Dedicating a full day to just one major theme makes a huge difference. But my biggest struggle with day theming is dealing with urgent client requests that ignore my schedule.

Do you pause your theme day to fix fires, or push them to the next day?
