Adventure is allowing the unexpected to happen to you.

The world is a book and those who do not travel read only one page.
Life is either a daring adventure or nothing at all.
Adventure is not the result of any distance; it's the disposition of the traveller.
To live is the rarest thing in the world. Most people exist, that is all.
Jobs fill your pocket, but adventures fill your soul.
I'm not afraid of storms, for I'm learning how to sail my ship.

The biggest adventure you can ever take is to live the life of your dreams.
