While travelling makes you more experienced, it does not make you wiser.
Travelling allows one to try new things like snorkelling, mountaineering and skiing, but it does not make one more wise because you could travel regularly for years and still turn out to be ignorant and culturally insensitive.
Judiciousness is not determined by how much and how many places you travel. It is determined by how culturally aware you are of different places you visit. Like slurping noodles in Japan is a sign of respect that the chef cooked well or dressing modestly in Saudi Arabia because it is a strict Muslim-majority country. There are some people who travel often but behave like idiots or do not respect cultural norms like how one Israeli tourist said that her money builds Thailand after she was told to remove her shoes due to cultural aspects.
Don’t get me wrong, I LOVE to travel. Travelling is fun, offers new experiences, and is an amazing rest. I love gaining new experiences that are enjoyable and memorable like rice planting, snorkelling and analyse archaeological evidence of how people lived in the past. But people should not equate travelling more with becoming more wise. You gain more experiences in your travels but it does not make you wiser.
