📖 A Chaotic Morning
Valentina was an event coordinator in San José. On the morning of an important corporate event, everything seemed to go wrong at once.
She had barely arrived at her kitchen when she realized she had run out of coffee. No coffee meant a slow start. She switched to orange juice, grabbed her bag, and rushed to the office. On the highway, she ran into a traffic jam — and then, in the worst coincidence, ran into her boss walking out of a nearby café. "Big day today, Valentina," he said with a smile. She nodded and kept moving.
At the office, she ran through her event checklist: decorations, catering, sound system. But the sound technician had run off without leaving any contact information. Valentina called several suppliers, but her phone battery had begun to run down. She found a charger just in time.
While searching her desk drawers, she ran across a backup contract she thought she had lost — exactly what she needed. A small victory. At noon, the costs began to run up faster than expected. A colleague had run out on his responsibilities at the last minute, leaving Valentina to manage the extra vendors alone. She didn't let this run her down. She ran over the budget one final time, found savings in two areas, and solved the problem.
The event was a success. "Don't run away from a chaotic morning," she told a younger colleague afterward. "Just stay calm and keep going."
