     Creativity is the ability to create inventions,solve problems or create a work of art using

an unusual or innovative(革新的)approach.Creativity is also a skill in high demand in business

and in many other forms of employment.All progress is the result of some sort of creative

act.Thus someone who can produce such acts on a consistent basis is a valuable addition

to any undertaking.

     Research has shown that too much passive media consumption at a young age prevents

the development of creativity.You might think that creativity is a result of high intelligence,

but that is not the case.Sure,it does not hurt to be smart,but you can be a smart robot

without being able to imagine new ways of doing things.On the other hand it's common

knowledge that traveling increases your ability to think"outside the box",because you

experience a lot of new things and different ways of doing things when you witness how

people from other cultures live.

     So what is the difference between surfing the web and watching TV and traveling?

Watching TV is very passive and your brain simply discards most of it.And it is as if it

has become cluttered(凌乱的)with useless information that it cannot really process.

     When you are doing things actively,by being there,by having a heightened sense of

alert,very positive things happen.For example,remember your last trip.Let's say you've

been to Tokyo.For most nonJapanese the experience of being in the city is very impressive.

Everything is huge.There are lots of people and technology is everywhere.Because the city

is new for you,your brain switches in"possibly dangerous"mode.You notice much more,

even tiny details.

     Now that your mind is open it also stores the information better,because of your aroused

state.All your input is stored with stronger emotions and is thus easier to recall later.That's

why you should travel or simply go to new places in your town.Actively observe how you

feel and then try to reproduce the feeling at a familiar place.This way you will learn to see

things with the eyes of a traveler.
