office, lab, and dorm room has an Ethernet connection to the university's computer network and a telephone connected to the university's telephone network The help desk is a telephone number that is answered 24 hours a day by a team of highly trained computer technicians, like Gunther, who can help users troubleshoot their problems When the help desk was first established, it was almost immediately overwhelmed with calls Gunther and the other help desk team members identified the following problems: Despite the fact that each technician had a different area of specialization, calls would be delivered to the different technicians at random Often it was not until a minute or more into the call that the technician could determine that the problem might be better handled by someone else At that point the call could be transferred (and the background information repeated), or the technician could take a stab at the caller's problem After a technician had explained how to a fix a problem, callers preferred to stay on the line while they implemented the solution; they didn't want to risk having to explain the problem (and the fix that was recommended) to a different person if the fix didn't work The result was that calls that should have taken only two or five minutes actually were tying up a technician and a phone line for as much as half an hour Another reason callers wanted to keep their technician on the line was that waiting times were so long that they didn't want to have to call back again if their problem wasn't solved The team decided to let Gunther implement a CT solution to eliminate these problems Here's what he did: Gunther began by building a simple database, using an off-the-shelf database product, that would track all the information relevant to every problem report Every technician's computer has access to this multi-user database, and the appropriate record is.

D T N ing world These were people who weren t just doing it well, but were doing it extraordinarily well, exceptionally well, and I was their student, absorbing every bit of advice and every bit of inner wisdom that anyone would share with me I called speakers and authors and interviewed them over the telephone, but there were also those whom I studied from afar I said earlier that you should gravitate not only toward like-minded people, but also toward people greater than yourself, people who are more successful than you are at this moment What I mean by this is that you should start studying the people who are living their dream people who are applying their extraordinary inner wisdom and unshakable faith to what they do Seek out people who you think are living their higher truth and greatest potential Then make a connection Read about them, watch their videotapes and CDs, find out what their personal philosophies are and how they practice those philosophies, investigate how they overcame adversity, and look for what drives them toward a greater purpose Meeting these dynamic speakers and authors in person was never my goal the goal was to gravitate toward them in whatever way I could because they were doing what I hoped one day to do for a living If I got lucky and met someone along the way, that was icing on the cake But typically, that wasn t the case For example, when I found out that Stephen King had written a book on how to become a successful author, I bought it I d never read even one Stephen King novel, but I had always been impressed with the way he got his career as a writer going and the solid relationships he had built within both the publishing world and the entertainment industry I set out to gravitate toward Stephen King, but I ve never met him and probably never will Did he influence me to want to write a novel and a screenplay one day Yes His book On Writing is one of the finest, if not the finest, no-nonsense, practical books on how to become a successful writer that I have ever read As writers go, I consider Stephen King greater and more successful than myself So, Mr King, if you re reading this, I ve added you to my life board of directors.
