Micro-Focus Sessions for Busy Days

I have very fragmented time but still need to do focused work. My typical day includes {{DAY_STRUCTURE}} with free pockets of {{POCKET_DURATION}} minutes. The work I need to focus on is {{FOCUS_WORK}} and interruptions come from {{INTERRUPTION_SOURCES}}.

Help me maximize micro-focus sessions:
1. Micro-focus mindset shift
2. Preparing tasks for short sessions
3. Rapid focus activation techniques
4. 5-minute focus protocols
5. 15-minute deep dive method
6. Context switching minimization
7. Progress tracking in micro-sessions
8. Combining pockets strategically
9. Creating micro-focus opportunities
