Going on exchange was the best decision I have ever made in my life. It shows that there is more to the world than the radius of 20km around your parents' house, which includes your high school and perhaps your university. Thanks to my exchange, I landed a 8-month internship in the country of my exchange (Canada) and ended up living abroad for a full year in total, making lifelong friends and memories. Meeting likeminded ambitious people from all over the world during my exchange has influenced my decision to pursue a masters abroad. Had I never been on exchange, I would not be typing this from London and I would most likely have opted for a masters at the UvA.
