Whenever I set out on a trip, passage 47 of the Daodejing always comes to mind.  I don't really agree with it, as is obvious from the fact of my travel, but it keeps things in perspective:

You can know all beneath heaven though you never step out the door, and you can see the Way of heaven though you never look out the window.

The further you explore, the less you know.

So it is that a sage knows by going nowhere, names by seeing nothing, perfects by doing nothing.

不出戶知天下；不闚牖見天道。其出彌遠，其知彌少。是以聖人不行而知，不見而名，不為而成。
