Maintain a positive attitude is the medicine to cope with adversity

There is a story:

There is a pair of twin brothers grow up with an alcoholic father. One of them became a drunkard, and the other was never drinking. A reporter asked one of the reasons why he was an alcoholic, he said, "Because I have an alcoholic father, he has a deep impact on me." Followed by the reporter asked the other brother why he never drink, he said, "Because I have an alcoholic father, he has a deep impact on me."

The implication of this story is that many environmental factors are that you cannot change, you cannot choose your parents, your brothers and sisters, your own children, the country you are born, the place you grow, your appearance, and your height. At Many times, you give, it may not has a return. Sometimes, you have not mistaken, but the unfortunate thing comes to find you.

All these things will have impact on you, however the implication is positive or negative, it based on your mind. And your mind is ability to control by you, you can change it.
