This reminds me of a quote from Lord of the Rings: "Not all who wander are lost."  I think growing up in such a structured society gives us moments of question and doubt as to whether we should move outside of the box and explore. It's hard to move...

What was it they used to put in maps at the edges of the known world?  "Here abide monsters".  We tend to fear the unknown.  I figure you have at least a 50/50 chance of it being something nice.

What a wonderful quote. Growing up by the sea I can relate very well to this. It reminds me of the many hours I stood on the cliffs as a child, gazing at the horizon, wondering what was beyond.
