You should try to explore ideas from a different culture if you can today: don't worry, it will be easier than you think. You don't have to polish off your passport and hop a flight to thailand! Even if you just listen to some ethnic music on the radio or eat at a sushi restaurant, you will get enough of a taste of diversity to make a difference in your day. Either you will cherish your own culture all the more, or get interested in learning more about someone else's.
