I own a small dairy farm it allows me to be outside , one day the driver of the milk truck and I were talking, He told me he served in the military for a while , got a degree in engineering, and was working in an office cubicle starring at computer screen , he didn't feel like he accomplished much. He made a big change and got a CDL and started driving truck, he felt he got more from that than his previous career and was happy. I personally have thought a change ,but never have changed. Another guy my age were talking one day, I spoke of changing careers, his comments we don't know what were going to do when we grow up ! Good luckl !!!!
