just travel.. i'm leaving on December 25 for Europe, and not coming back till June... its not to expensive, if you know who to find cheap flights (easyjet, ryanair) and are willing to live in hostels.. i've only spent about $1000 on flights from the US to europe on to india, and back... so its definitely doable
and don't let people tell you to save your money to pay off future debts... worry about that later.. enjoy your money on yourself right now.. because you're not going to be able to again for 7-8 years
