For many people – especially those juggling (兼顾) family and work at the same time --- it can be difficult to stick with a college degree. Kathy Bitzthum thought many times about dropping out of her accounting program at Iowa State University: She had two children and a job at Electronic Technology Corp. She’d only enrolled in the first place because her boss would offer her a promotion if she took a few accounting courses.

Because she only had enough time to take one class at a time, it took her seven years to complete the courses her boss asked her to take on. She received the promotion as her boss promised and wasn’t planning to continue a degree. But a request from her father, who was dying of cancer, made her think twice. He said to her, “Kathy, why don’t you just keep going and get your degree?”

Before he passed away, he made her promise that she would finish it. And he made her a promise in turn. Vitzthum’s parents had agreed to give each of their children a valuable gift when they graduated from college, and Vitzthum was obsessed with an antique she’d come across and knew that she couldn’t afford. After she promised to graduate from college, her parents bought her the antique. Her father told her, “I’m not going to be around when you graduate, so I’ll give this to you now. But it doesn’t _________ until you graduate from college.”

Since then, Vitzthum has looked at that antique every day and remembered the promise she had made to her father. Despite a hectic life as a wife, mother and full-time employee, she’s taken one course every semester for the last 19 years. And finally, at the age of 48, she graduated with a bachelor’s degree in accounting --- and she was excited to accept full ownership (所有权) of the antique that she’d borrowed for more than a decade.
