Why does the alchemist choose Santiago (the boy) as his pupil over the Englishman in Paulo Coelho's The Alchemist?

In 's
, the alchemist chooses Santiago over the Englishman to be his pupil or
"disciple" because the Englishman believes that wealth in the world is found in gold.
He believes that if he reads enough books and talks to the right people (like the alchemist), he
will be successful. The Englishman does not recognize that each person has a Personal Legend and
he cannot make himself listen to or recognize the universal languagehe does
not see omens or hear nature speaking to him.

However, Santiago (the boy) has
a dream, and while he first believes that the dream involves discovering treasure at the
Pyramids, he is willing to listen to the teachings of others, like Melchizedek (the King of
Salem) and the alchemist. Santiago is able to realize that his happiness does
not depend on material wealth. It is only because he is so open to the
universe that the universe is able to speak to him and guide him to be much more than he had
ever imagined. He is able to speak the universal language, be one with nature and the Soul of
the World, and ultimately witness that it is all a part of the Soul of God. Santiago also
realizes that love is the greatest treasure in the world. The alchemist knows that the
Englishman could never do these things.

The Englishman could ever appreciate
the natural world or be humbled enough to believe that something as simple as nature could guide
himand the alchemist knows this. The Englishman has tunnel vision, and without true
"vision," he will never swerve from the path he has decided to
follow, therefore, we can assume he will never be happy.
