Your list.

It would be extensive, follow your passions and ignore time or energy to pursue. Likely, it includes work, not because you need to but because you find it meaningful.

You may:

Start a business.
Lead a non-profit.
Consult, teach or write.
Manage rental properties.
Travel a month abroad.
 Host family at lake all summer.
Actually balance kids, aging parents and well-being.

Think of your list if you retire at 65.

Look different?

Yet, age 65 is the focus for many.
