In my opinion,Selfish is character of human from a child when she/he has feelings and knows how to compete with others.Selfish is the emotion that in people's heart.Everyone has little selfish,it depends on people’s family and school education background.
If everyone’s selfish doesn’t hurt other people and have no harm to the society.Why not be selfish?
Selfish represent sense of achievement.
To protect one to survive better in the society.
Selfish can also reveal how much you love your friend,family members.
when we are in school,if you don't study hard,will you get your progress?Because you want to surpass yourself and others,so you may be study in selfish.
Because you have want to survive in the job or business market,you have to be selfish.
When you love a boy,and another girl also loves him,will you give up?
Happiness need effort,if you don’t do any action,you will have to love another boy in next cross.But if you can’t find,you will be sorrow forever.
Because of selfish,the society develops,and man can achieve great success.
But when you are selfish,think over and over again,will this hurt other people?Is fair to other people?How can I be selfish,get what I want and can also help others?
