people often complain about their sufferings,especially when others got what they themselves didn't.most people are apt to totally believe in their ability to achieve the goal,no matter how humble they are in front of others.so when others got a better score they may say hw can it be this,i don't think he is clever than me or he works harder than me,it is unfair.

where is jealous from?i think it results from feeling of unfair.if we reduce the possibility of feeling unimpartial,jealous in the world can be reduced to a lower level.nothing that exists is unreasonable,if the truth is standing just there,how can we say it's unreasonable.people may say this idea is kinda of pessimistic,i do not agree,only when we stand on the basic of the truth,not the complaint,shall we have the chance to jump high in the next step.

so,never complain what it is now.but accept and change it then.
