This is totally new to me and it will take a while for it to sink in, but I see the connections in purpose and stage of life, although in different combinations:

-Be a decent human being
-Do/contribute something for yourself and others while you
-continue to grow as a person and
-enjoy yourself.

The stages of life is where I don´t see a separation of the last three.

-Learn and prepare yourself (to produce)
-Produce work (and children) most of life, then at different ages people work on self-development and keep learning and deepening their self-realization until death.

Maybe I´m a 2-speed:  Just learning and doing.

Our knowledge has surpassed our wisdom. -Charu Saxena.
