G. Mark’s Answer
When you say, "working with," I assume you mean the clients rather than co-workers. The key to dealing with all the various challenges people have is to first realize that we are all challenged in some way. Your first impulse may be to be surprised or disappointed or critical of some aspect of a person's personality or proclivity. The point is that these are all relative to framework we come to a case with -- that is, our own personality. When I was young, I approached all people with using my own experience as a reference. This not only limited me, but truly limited my ability to engage, connect and understand others. Distancing yourself from this reference is not only difficult, but absolutely necessary. You cannot be useful to others if you limit yourself to your own frame of reference.
