Business lessons in adversity. Yesterday was a day that should have driven me up the wall. I watched every photo I had taken from the fall of 2005 through the fall of 2007 permanently disappear in a computer failure, while I was trying to copy them to an external drive. A squabble on a discussion list turned ugly in a way that could have serious repercussions for the future of my business. I left yet another voicemail with the editor at a big NY publishing house who should have had a revised contract on my desk in June and has not been answering phone calls or e-mails.
