How did morrie achieve wisdom?the process of how morrie achieved wisdom

Much of Morrie's wisdom came from careful observation of
and reflection on the lives he saw around him.  He lived a life filled with myriad
powerful experiences as a child of the depression and also clearly a very observant
child.

Because of this experiences observing patients in a
mental hospital and seeing people working in horrendous conditions like his father and
being unable to find work in the depression, Morrie developed the philosophy of
embracing life and sucking the marrow out of its bones, experiencing it
fully.

He demonstrated this attitude towards his students
by giving them the same respect he gave to everyone, continuing the idea that he had
something to learn from everyone and by so doing he did in fact learn from
everyone.
