I urge you to travel. As far and as much as possible. Work ridiculous shifts to save your money. Go without the latest iPhone. Throw yourself out of your comfort zone. Find out how other people live and realize that the world is a much bigger place than the town you live in. And when you come home, home may still be the same. And yes, you may go back to the same old job, but something in you will have changed.
And trust me, that changes everything.
