I got this philosophy from the most unlikely of places, a youtube comment! Not my own:
Travel isn't always easy so why do it? If you are afraid of leaving your comfort zone, let me tell you one thing, life is too freaking short. One day you will die. It might be eternal darkness and silence or something beyond our knowledge. All the things you've achieved, all your fears , embarrassments will be gone. Nobody (2 generations max) will remember you. You will just be someone out of the billions of people who lived on this planet. Travel is a way of both escaping the mundane and gaining an exciting education. If you are lucky enough to have the freedom to travel it would be CRAZY not too! You will not regret it.
