Nowadays,there are so many rules around us:School rules,public rules,traffic rules even rules to be a successful person.Therefore,much of us would woder that are these rules helpful for us?
The answer is some would but some not.Let’s guess what would happen if there is no traffic rules?Of course,people cannot control the road orderly and there must be lots of traffic accident.
But also,there are too many unreasonable rules to prevent us achieving goats.For instant,many company refuse to employ women because they think women are not strong and smart as men.It is a fause rule,but we cannot change it.
In a word,we should obey the public rules to make our life orderly,but if it is a fause rule,we should refuse it and respect our principles.
