Start With Some Personal PR, Then Go International
I am currently studying in Salamanca, Spain for the month of July, and there have been several times when I felt that a little dose of PR would help anyone traveling abroad.
Americans have a little bit of pressure I think when they go over seas. While everyone I have encountered over here has been very nice, there are a select few who I can tell are expecting all the Americans they encounter to fall into a particular stereotype.
For instance some students, while here, have been asked how many hamburgers and french fries we eat every week, because many people think that is all that Americans eat. I have also heard that many people think Americans are very loud. So knowing that there is a certain percentage of the population around the world that feel this way is what makes me think that, when abroad, every American should think as a PR professional would.
