How to release yourself when you feel bad?

Everyone meets bad mood in the life time. There is an lod proverb said:"Life is mostly as one wishes thing" which express the frustrated life. We may fell bad when some friends leave us, when we quarrel with other men, when we see or hear painful affairs, when we meet difficulties in the job, when we can't be understand by our colleague or leader,etc. So it's quite nomal when we confromt pressure and bad emotion. However, there aslo has another idiom said: Pleasure accompanied by sorrow. Therefore, we should see towards the sunny side. Optimism is more and more important to modern people who live in such a high development and extreme competitive sociaty.
No matter whom you are, you are bound to pressure and then the pressure transfer to bad mood. However, fortunately, I have many way to reduce all kinds of pressures.
In the first place, travel is the best way. No one feel boring when he goes to a strange city or country. The new things, beautiful scenery, different culture always catch man's curiosity. I'm excited when I go to other cities every time, especially when I sat on plane. The blue sky and white cloudy sea always attract me so much. But it's really a great consumption to have long time journey.
Second, cry is also a good abreact way. Many people argue that woman is made by water. Of course, you'll feel better after crying. Certainly, litter pressure don't need to weep.
Third, Many people chose going shopping crazily, the things they bought sometimes lying down the bottom of man's graderobe or filling with dust. This way also waste considerable money but can cure some people's pressure.
For me, I sometimes choose to visit other cities. And a great part of the pessimistic time, I choose to write blog, read book , listen to music or chat with my friends etc. I always express my sigh with emotion in my essaies.  After finishing writing , I felt better then.
Finally, if you like to take photo, i argue that it's really a good way to reduce the pressure. I take many photos about building, scenery, sky, cloud, river, coffee cup and shop, etc. I recorded down all the beautiful life in my camere, then I began to delight.
I always like this idiom: If you are easy ,the life is easy. Remember. settlements are more than problems forever. Keep optimism,and you will find the life is colorful.
