Everyone wants to do well ,but sometimes it's really very hard .You always don't know how to deal with the trivials in your life ,and the trivials will influence your mood ,even though it's very very small in other people's eyes.To be honest ,I want to have a good mood every day,but usually the heavy homewok ,the unnecessary mistake,even the small  misunderstanging make me in a bad mood .When suffering those trouble ,how can I do ?Maybe it's very easy to solve ,that is forgetting them temporarily,having an enjoyment with your interests,and then do your disliked things with a good mood ,ok ,just like that ,and come on .
