What should I do if I am always angry? Encounter square dancing and low quality and looking for trouble, always have no good solution, old angry how to do?

The old angry this to their own but not good, always think they are right, others are wrong, you are not into a misunderstanding, to adjust their own mindset. There is such a story, one day a crow angrily flew out of the forest, met a small bird, the bird asked him why he was angry, he said these birds are too much for me to sing the song is not good, so he wanted to leave this place, the bird said, since you can not change others, then change yourself, do not change yourself to where it is also the same. The crow fertilized back into the forest. That is, we can not change the environment, change yourself.
