It's the Best Form of Education
Traveling and seeing a world outside what you are accustomed to gives a vast source of knowledge and education that can't be gotten anywhere else, much less within the four walls of an educational institution. It also goes beyond the knowledge you gain from reading books or hearing stories about it. The experience of traveling teaches sociology, psychology, politics, history, economics, geography etc. in a hands-on way, that'll leave you with memories too prized to be forgotten.
You Need to Take a Breather
Traveling is one of the best ways to relax and unwind, and to just take a break from the normal course of your life. It's a great way to take a breather, experience new things, and recharge your batteries to later increase your work productivity.
It Pushes Your Limits
Traveling takes you out of your comfort zone and will help push your limits as well as refine your social skills. From figuring out maps and how to get to various destinations to fending off potential scammers, you'll honestly be surprised at just how resourceful travel can make you. Also, there is that satisfying feeling of fulfillment it gives when you are able to successfully figure out how to do things you have never done before or never imagined you could even do.
It Helps Open Your Mind
This has more to do with how much travel exposes you to new people and experiences. No matter how rigid you were, you'll gradually see yourself becoming more open to things, people and experiences. There's just something about being in a different place, surrounded by people from diverse backgrounds and walks of life that opens up your mind in way you never even thought possible. It just refreshes your perspective.
