If you are a religious reader of this column, then you know that I do not write all the articles. No, that would be just too boring. So to add “spice” to the column I often entertain the works of guest columnists. Actually, the reason for including guest columnists has less to do with “spice” than it does with general interest. When I receive articles from column readers, it gives me insight into their professional experiences, and in turn I share what I have learned with you.
