Anyone here work in public relations?

[LaraMN]

I'm trying to narrow the scope of my studies so that they pertain to a more specific segment of the local job market. I'm majoring in communications, but have been dragging my feet about what area of comm. I'd actually like to work in.

I'm starting to think that p.r. might be the field that my interests/strengths gravitate toward.

I'm curious to hear from anyone who has actually worked in a public relations capacity.
What did/do you do?
What are the aspects you find most positive/negative about the field?
What might an "outsider" not realize about the nature of p.r. work that is essential to be aware of?
What type of skills are most essential to functioning effectively in the field?

tia to anyone with any insights!
