Me I am retired, so my tiny two cent comment, Our lives change from time to time, we grow, we get scared, we learn or relearn fear, health deteriorates, health grows, family grows, thus we with our life grow. Changes happen, some good, some bad. it is how we view the change, alone, group, or corporate, jobs are going to change also, I would sy never stay in a job you detest, because you will carry that detest around you like a ball and anchor dragging yourself and those around you down.
