What was the most useful criticism you ever received?

"I value all feedback that I receive. I treat it as a gift. There is one time that stands out in my mind. A few years ago when I was a Compensation Analyst for a large healthcare organization, I had a division administrator approach me about a recent email communication that I had sent his way. He approached me in person because he wasn't able to decipher a lot of the information that I had sent him that he originally requested. In our conversation, it became very clear that a lot of the terminology I had used was hard for him to comprehend. So we talked through the information that I had sent so it was clear to him. I learned an important lesson from the feedback that I received from him and now I try to be cognizant of the way I communicate to different people."
