great post Ewan as a parent I can't tell you how much I value what the teachers in my children's school do I think as a society in general we forget how much teachers give great value to society as a whole. As a Calgary Marketing company I tried to provide great value to my students as well I am always trying to learn new things for them and sometimes just that part of my business takes up most of my time. nowadays my two young girls 15 and 18 it's hard to believe how fast they grow and how smart they are as I tried to challenge them also with problem solving, new concepts and new ideas. Once again Ewan thanks for the great post I will be following you a regular basis now on.
