When I left, the search for my replacement took a long time. Much longer than I’d have preferred, and to an eventually unsatisfactory conclusion for everyone involved, I believe. I contented myself with the knowledge that my skill set was sufficiently wide in breadth and complex in nature that I was hard to replace. I used this to buoy my ego. ALthough I had sympathy for the people I was leaving, and the one I left in my stead, it felt good to be needed and wanted, and I was proud that I could fill that role like no one else we’d found.
Such is the folly of the unwise, I’m afraid.~ Matt Simmons from, http://www.standalone-sysadmin.com/blog/2013/02/and-when-you-gaze-long-into-an-infrastructure-the-infrastructure-will-gaze-back-into-you/
