pessimistic与negative的区别

1.但是,伤感悲观的人常常花费大量精力叹嗟自己跌倒站起的过程.
2.记住,快乐的人总会把“私人啦啦队长”（给自己加油鼓劲的人）做为朋友.但是悲伤的人会把自己夹在那些隐藏自己快乐心情的人之间.
3.从某种程度上讲,快乐的人就像追逐目标的狂人……而悲伤的人不明了他们自己为什么总是执着于此.（这里的it不知指什么,如果省略号省略了些句子的话,就这样翻译吧）

Pessimistic people always assume the worst while facing a problem,which will usually cause negative consequences on their life; because they only see the bad parts and thus lose the courage to confront the problems.And,by contrast,optimistic people see more chances when they are in trouble; they believe that they can finally conquer the obstacles in front of them.This kind of positive attitude can keep them calm and grasp the opportunities needed to get out of trouble.Moreover,studies show that pessimistic people are more likely to develop chronic diseases than optimistic people.From the contrast above,we can get the conclusion that to be optimistic rather than to be pessimistic is essential for everyone to live a happy life!
To be optimistic we should know that life is equal for everyone and the difference is what we do.With this kind of idea,you will not waste your time in complaining,and instead you will manage to find a way out.
