IMNHO, looking to another country or place to find inner peace probably won't work. You're looking for an external solution to an internal issue.

If you really want to enjoy your travel and get the most out of it, I'd recommend finding that inner peace first - some find it in meditation, some in one of the various religions, some in simple solitude. But you should find happiness with yourself here and now if you want to enjoy happiness in other places and at other times.
