Adventure is worthwhile in itself.

The biggest adventure you can take is to live the life of your dreams.
Adventure is allowing the unexpected to happen to you. Exploration is experiencing what you have not experienced before.
Every man's life ends the same way. It is only the details of how he lived and how he died that distinguish one man from another.
Life is an adventure that is best lived boldly.

Life is short, and the world is wide.
Life is either a daring adventure or nothing at all.
Adventure without risk is Disneyland.
To live would be an awfully big adventure.

The purpose of life is to live it, to taste experience to the utmost, to reach out eagerly and without fear for newer and richer experience.
Adventure is not outside man; it is within.
Adventure is not in the guidebook, and beauty is not on the map. Seek and ye shall find.
I am not the same, having seen the moon shine on the other side of the world.
Adventure isn't hanging off a rope on the side of a mountain. Adventure is an attitude we must apply to the day-to-day obstacles in life.
