"Your 20s are your selfish years. Old enough to make the right decisions and young enough to make the wrong ones. Be selfish with your time - travel, explore, fall in love, be ridiculous and silly, stupid and wild."
Travel is more than a seeing of sights; it is a change that goes on, deep and permanent, in the ideas of living.
Why do you go away? So that you can come back. So that you can see the place you came from with new eyes and extra colours. And the people there see you differently,too. Coming back to where you started is not the same as never leaving.
