Life consists of choices: choice of study, career, boyfriend, political orientation, and eventually the choices that come with adulthood. But you could also choose to put adult life on standby, take a year off your calendar and see the world before it's too late.
 
Or to put in another way - why worry about retirement savings and designer kitchens when you can:

• eat perfect pancakes at a breakfast diner in New York
• go diving amongst moray eels off the coast of Kenya
• stuff yourself with curry and check out the Taj Mahal in India
• work as a bike messenger in Sydney
• laze in a hammock all day long on Fiji 
• learn to speak Spanish in Buenos Aires
• party the night away on one of the islands in Thailand
