Obviously I'm not a travel expert, but it really is true that you learn so much in just one trip! Besides various travels around the U.S., and a one-day-Niagara-Falls visit to Canada, the only other time I have been abroad was when I traveled to Greece with my cousins, actually just this past April! We visited Madrid (a lay-over), Athens, Santorini, and Rhodes over the course of 10 days, and lots of my travel ideas/tips and such are coming from that experience! Just a quick fast fact kind of thing!
P.S.- Comment below if you've ever visited those places in Greece, or if you want me to put up some pictures/videos from the trip! I'd love to know!
