Why travel you ask?
Everyone is working a 9-5 job, paying rent, paying their bills, spending money on stuff they don't need or want while doing the same thing over and over again. And then at the age of 65 (as it is here in the us) you get to retire, take your pension, 401k or whatever and travel the world. So basically you get to do what you want when you're old? Kinda sucks. Imagine trying to hike up Manchu Picchu at 65, with your fake hip, blown out knees and an O2 tank. Not fun right? (not to say that there aren't old people to hike up there) but hell they're in better shape than you and I.
You spend most of your youth working for something. Some huge reward you think you're gonna get at the end. Truth is you're not living until you see the world. When you look back on your life what do you want to see? That you worked a 9-5 job, made a great sexy 401k that will make your friends jealous? Or that you managed to go out and see the world before you become old and decrepit?
Travel is the one thing you spend money on that will make you happy and richer in a sense. Don't you want to be happy? They say knowledge isn't only in books, it's in where you have traveled, where you have gone and seen.
