I think that often it's the journey that prepares you for the destination. For example, in LOTR, we see that throughout the story several characters learn many things, about both themselves and the world around them. I'm pretty sure that if Frodo and Sam had somehow been able to take an easy road with no difficulties or hardships along the way, they would never have developed the strength (both physical and emotional) to make it through Mordor to the fiery mountain.
