Many people chase achievement, assuming it will lead to well-being. They should reverse that order of operations. Without going too far out on a limb, I believe almost everyone would like two things from their jobs and careers: success and happiness.
I believe a similar logic applies to how we should approach retirement. In retirement, we often mistakenly believe that success in retirement is tied to our finances. However, reversing that order to focus on well-being (mental/emotional, physical, social, and spiritual) will lead to greater achievement (success and happiness) in our post-career lives.
As this applies to work, in retirement our work is not focused on achievement for the sake of moving up the career ladder, but it tends to be more focused on the impact we are making and how that impact translates into making our lives more fulfilled.
