Your dollars will go pretty far
The dollar isn't as strong as it was ten years ago, but it’s regained strength this year, even against the dreaded Euro. That makes traveling overseas cheaper. And visiting countries whose currency has slid against the dollar will help even more. Choice destinations include Australia, Canada, Southeast Asia, and South America. Go now, spend less, and do more.
You'll regret not doing it when you're old
No one ever comes back from time abroad and says, “Wow! Traveling sucks!” If you wait long enough, eventually you'll probably get married, have kids, buy a house, and really set down roots. And those things are great. But you can't just up and ditch them on a whim when you're 35.
