What's an example of when you changed your mind?

When I was in college, I was certain that I wanted to pursue a career in medicine. As the years went by, though, I began to realize that although it had been my long-term goal once upon a time, my heart just wasn't in it anymore and my values had changed. After some soul-searching and contemplation, I decided to switch paths and devote myself to the world of business instead. To this day, it truly has been the most life-changing decision I've ever made!
