Fight the stress with relax. If you are moslem, do a duha prayer. Or listen to Quran recitation.

Other way, play a game, Xbox, PSP, PS3 or whatever. But choose the right game and select the easiest level. So you can get "master" result.

Try to watch funny videos, movies or clip. Ice Age 3 is funny enough.

Go to a place that you never been there before.

Call your family.
