If you don't have a permanent home you must be at home in your own skin and with a suitcase of outfits you wear very often. You read the books that happen to be on hand when you don't have access to a library in your language: you find things you had been meaning to read, things you had never heard of, things you'd not normally read, classics you finally reread.
Reading The Alchemist by Paulo Coelho has taught me:
+ Wanting to know the world is so much more important than knowing G-d and learning about man's sins.
+ To sleep the same place every night of your life is a burden.
+ Other cities and other lovers offers us other opportunities to be happy.
+ The world is huge and inexhaustible.
+ It's the simple things in life that are the most extraordinary.
+ Being too consumed from the judgement of others leads to an unfulfilled life.
+ We sometimes feel bitter and distrustful of people because one person has betrayed us.
+ We must think of ourselves as adventurers looking for treasure.
+ Self-contentment trumps money and riches - "This candy merchant isn't making candy so he can later travel or marry a shopkeeper's daughter. He's doing it because it's what he wants to do."
+ The bad tends to accentuate the good. "Maybe G-d created the desert so that man could appreciate the date trees."
+ Usually the threat of death makes people a lot more aware of their lives.
+ "No matter what he does, every person on earth plays a central role in the history of the world. And normally he doesn't know it."
