I am trying to compare Empire of the Sun to The Alchemist. What would be Jim's personal legend?

I think
that Jim's Personal Legend would be survival.  The Personal Legend is what one is meant to do:
...There is a force that wants you to realize your Personal Legend€¦[but] in order to find the
treasure you will have to follow the omens.  For Jim, his would have to be survival through his
ordeal.  From a life of comfort and privilege, he is hurled into a world...
