I deeply believe that almost everyone wishes to own a good mood,with which people can better and more effectively complete their work or studies,even any affair they are handling.Therefore,to own a good mood is very important.
However,there are always some factors that will make people in a bad mood,reasons are quite complicated in all directions.Maybe,some people don't do well in their jobs,such as not successfully helping the company sign an important contract,or not gaining a high score in the exams.Of course,some family matters will also make people feel not so good.
Therefore,to set people's mind become a difficult issue.They key to keeping a good mood is to have a optimistic attitude,espeically when people are facing some problems they are not willing to.In addition,never repeatedly thinking about the unhappy matters,instead,just thinking about the pleasant things,and I also advise everyone laugh loudly when getting up for it can help you keep a good mood all day long.
我深信几乎每个人希望拥有一个好心情,因为它可以使人们更好更有效率低完成他们的工作或学习,甚至是任何他们处理的事情,所以,有个好心情是非常重要的.
但是,总有些因素会会给人带来不快,原因很复杂并且来自各个方面.或许是一些人没有很好地完成他们的工作,比如没有成功地帮助公司签下一个重要的合同,或者在考试中成绩不理想.当然,一些家里的事同样会使人不能拥有一个好的心情.
所以,调整人们的心情就变成了一个难题.保持好心情的关键是拥有一个乐观的态度,特别是在处理他们不愿意处理的事情时.另外,千万不要反复地去想那些令人不快的事情,相反,应该想那些使人高兴的事.并且我建议大家在起床的时候大声的小,因为这样能使你一整天都有个好心情.
自己写的,供楼主参考.
