Those of us who are members of the Traditional, Baby Boomer, and Gen X generations can remember the good old days when we could choose what to display on our office credenza and desk to show a little personality: A picture of a favorite pet, our kids or grandkids, or our significant other. Perhaps our favorite sports team paraphernalia was proudly displayed on a bookshelf. Maybe a trinket brought back from your European vacation sat nestled among the business books on our bookshelf.
