   "summary": "Tom is currently focused on managing a new project with a tight schedule. After a team meeting on June 25, 2025, he realized the original deadline of December 15 might not be feasible due to backend delays. Concerned about insufficient testing time, he welcomed Jerry’s suggestion of proposing an extension. Tom plans to raise the idea of shifting the deadline to January 5, 2026 in the next morning’s meeting. His actions reflect both stress about timelines and a proactive, team-oriented problem-solving approach."

+Dialogue:
+assistant: [10:30 AM, August 15, 2025]: The book Deep Work you mentioned is
+indeed very suitable for your current situation. The book explains … (omitted). The author suggests setting aside 2–3 hours of focused work blocks each day and turning off all notifications during that time. Considering that you need to submit a report next week, you could try using the 9:00–11:00 AM time slot for focused work.
