It is in the journey. All the places that he went, all the people the met and all the of the things that he experienced were what made him, him. The journey is a sense was what he was looking for.
It is more about the journey than the final destination. We as people need to live that sentence out. Way to often in life we set a goal and we will not let anything stop us from achieving it, and this goal may take years, months, weeks or even days but we all to often forget to stop and smell the roses. We forget to appreciate the journey that we are on, we forget to look at all the good times or even the bad one that come out it because those more often than not the events, the people and the experiences that make who we are today.
In a way it is like, living your life to fullest but I think is more than that, we just to acknowledge every moment, because who know maybe you won't reach your goal but that might not always be a bad thing, if thousands of little perfect moments came out of the journey it is okay to fail to reach the destination.
