enter retirement with only a vague idea of what they’ll do with all that free time. Or they have some specific ideas—typically trips they want to take—but only for the first year or two. So after a while, they tend to find themselves adrift, feeling aimless and maybe even itching to go back to work, the one place they know they’ll have a built-in sense of purpose, belonging, and accomplishment. In the worst cases, this sense of aimlessness can even lead to anxiety and depression.
