I have worked as an IT consultant for the last several years, more recently with my own company. Some of the tasks handed to me during that time seemed at first to be impossible to solve. There was just too much to grasp. It occurred to me that this was no different than other types of work I had done, but was merely a similar machine composed of different parts. My work for the 10 years previous had been in electronic repair up to including the repair of industrial and broadcast television equipment in the days when computers were beginning to rule there as well.
