For others contemplating retirement, follow mission's good example and see it as a good opportunity. The obstacle is that we are all encouraged to see our organization jobs, whether personal businesses or working for others, as our identity. Identify those aspects of your life that have always tugged at you and have never found a place in your work life, and explore them. I have seen a friend or two who have hung onto even an antagonistic workplace, taking the daily battle as their identity. You can do other things and draw on your experience. Just a pep talk for those confronting this change.
