Well i can assure you although i usually have and work out of an office in some cases two offices, i have always been to all intent and purposes site based. I've rarely if ever been tied to a desk/bench, rarely wear a shirt and tie, i don't do cretins, and never considered myself being in a pigeonhole, and certainly never been what can be classed as miserable in my work, over the 40 odd years i've been in this game. In fact it's been quite the opposite!!
Oh, and i have always earned more than decent money, doing what i have always enjoyed doing, ...and seeing the world in the process. I've made good use of the many qualifications i obtained, they are in my opinion, the tools and passport to success in life. It's up to the individual how high or low that success can go....
