Travel to change, not of place, but of ideas. Travel far away to feel the power to choose if you are satisfied with what others have done for you. Improve yourself. If you don't live to travel, you don't serve to live. There is nothing like going back where nothing changed to realize how you have changed. Who ask you the reason for your trips, say to them that you ignore what you are looking for. The only search is the experiential one. The best university that exists is traveling.
