Traveling lightly—both without physical stuff and without mental baggage—will serve you well. Over the years, I’ve tried to explain my thinking around these points via blog posts: One series on physical practicalities and tips is, Travel Gear. And, another series about the mindset of traveling is called, Parkour Travel.
