Albert Camus said this quote

What gives value to travel is fear. It is the fact that, at a certain moment, when we are so far from our own country … we are seized by a vague fear, and an instinctive desire to go back to the protection of old habits … this is why we should not say that we travel for pleasure. There is no pleasure in traveling, and I look upon it more as an occasion for spiritual testing … Pleasure takes us away from ourselves in the same way as distraction, in Pascal’s use of the word, takes us away from God. Travel, which is like a greater and a graver science, brings us back to ourselves.
