I'm watching Mad Men and the boys are going after the Honda business. Of course, one of the partners -- who fought in the war -- doesn't want to work with Japanese. This of course, doesn't make sense but that's another topic for another day.
What his story line reminds me of is the fact that in PR, we typically don't get to choose our clients. We go where the budgets are.
However, when stars align and work comes in the door that's of the nature that you really want to work on, it's a win win situation. Of course, for me, that work would be for a sports team or say doing PR for Apple or Google.
In the end though, enjoying what you do is important and sometimes you have to put aside petty feelings and ignorant beliefs for the greater good.
