About this section in the alchemist

I think Santiago realizes that he should pursue his dream of going to Egypt, regardless of the odds. The merchant opens up to him about his own dreams and it touches Santiago. He feels bad for the merchant because he doesn't want to pursue his dream. Some time passes and Santiago finally has enough money to go buy sheep and go back to Spain. However, he realizes that he may not ever be bale to go back to Egypt ever again. Santiago could always become a shepherd, or a merchant, but he may never get the chance to see the pyramids if he leaves Africa now. This realization allows Santiago to continue pursuing his personal legend.
