Travel can definitely be a mode of childlike exploration… especially if you’re traveling in pursuit of exploration and learning!
But I don’t think travel is the same for everyone. I’ve met lots of people who are content staying where they are and who learn and grow fine without traveling. For me, I need to be in constant motion. And that’s why I choose to travel so lightly. It feels incredibly freeing to grab my backpack and GO, knowing that I have everything I need right there. I don’t feel weighed down by my possessions (physically or mentally!).
