英語ストーリー（english story）

Title: The Initial Step to Success

When Mia started her initial job at a travel agency, she was both nervous and excited. Her initial reaction was to doubt herself, but she remembered that every expert was once a beginner. In the initial stage, her tasks were simple—answering calls and helping with bookings.

Her manager, Mr. Tanaka, told her, “Your initial impression matters. Be friendly and helpful.” Mia smiled and nodded.

Each employee had to write their initials on reports they checked. Mia carefully initialed every form she handled.

Through trial and error, she learned quickly. She made her initial decision to stay late and study the company’s travel packages. Mr. Tanaka noticed her efforts. “You’re improving a lot. This is just your first step.”

Eventually, Mia was promoted. She remembered how important that first step had been. It was her primary reason for working so hard.
