Adventure is a path. Real adventure – self-determined, self-motivated, often risky – forces you to have firsthand encounters with the world.

The only way to deal with fear is to face it. Embrace it. Because fear, after all, is just a feeling. And feelings can't hurt you.
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.
