In "Contents of the Dead Man's Pocket," how does Tom's life change as a result of his ordeal on the ledge?

In this story, the ordeal on the ledge (and what happens
after Tom gets to safety) changes Tom's life by making him realize what is truly
important.

At the beginning of the story, Tom thinks that
work is the most important thing in the world.  He is willing to essentially ignore his
wife so he can get work done.  But his ordeal on the ledge changes that.  He realizes
that his work really doesn't matter.  What really matters is the people in our lives and
our relationships with them.

By coming close to death, Tom
realizes what is truly important in life.
