The purpose of an internship is to provide a real life experience of what a typical day in the office is going to look like. I knew that before going in and that was exactly what I got.
I was sort of nervous for the work however, seeing that I hadn't heard of Campaign Asia-Pacific before my internship and I didn't know how they wrote their articles. Since I've been here for a few weeks, and gotten used to a working schedule, I can now say that I have had a fair share of experiences when my boss or co-workers have told me that my pieces were either on-point or needed improvement in some areas.
Learning how to accept criticism is extremely important in these situations, and shouldn't be taken personally. One should remember that criticism is given so that you can improve. Like the title says, you're not always going to be "perfect".
