I started un-jaded then I came to the same conclusion as you two. I kept going though and I'm changing my mind again - the world is not all the same, and there is plenty of opportunity for adventure. Maybe I'll change my mind again, I don't know everything either, but I hope I don't.
I don't know exactly what you guys did or didn't do, but my advice would be to adjust your strategy for where you spend time, and push yourself to pay closer attention. Maybe learn another language if you haven't already so you can really dive in.
