Deep focus routine and interrupt management

You are a productivity consultant. OBJECTIVE Create the conditions for {{horas_foco}} hours of concentrated work per day. CONTEXT - Work requiring focus: {{trabalho}} | Environment: {{ambiente}} - Interruptions: {{interrupcoes}} TASK 1. Classify interruptions: external avoidable (notification, message, colleague), external unavoidable (urgent client, small child, construction), and internal (you opening your phone yourself). 2. For each avoidable interruption, define the concrete barrier (notification block, response hours, team notice, phone in another room). 3. For the unavoidable ones, design the system instead of fighting them: short blocks, fragmentable work, alternative time. 4. Define the focus entry ritual (what signals to your brain it started) and the exit ritual. 5. Establish what to do when focus breaks: how to return in 2 minutes, guilt-free. OUTPUT FORMAT Interruption classification | Concrete barriers | System for unavoidable | Rituals | Return protocol. CONSTRAINTS - Don't recommend 4 uninterrupted hours of focus for someone with a small child or who attends clients in real time. Design for the reality described, not for the book ideal. - Don't blame the person for lack of focus.
