Some people think that it is better for parents to set strict rules for their children to acquire success. However, in my opinion, strict rules will not give their children a positive effect for their future instead of reaching for success.
To begin with, rigid rules make children be against to them. The more the rules are harsh, the more desirable for children to get out of the world where they cannot do anything what the want. For instance, my brother used to be on his phone all day long, so my mom made a rule to turn his phone in before he goes to bed. He seemed to follow it well. However, he got up early in the morning and snuck his phone out. It shows that it does not help children to change their habit; it even make worse since they find out other ways to do things.
On top of that, there are other ways to fix things. Instead of making everything bad to children, there should be fun things to go with. For example, making goals for them to achieve, and give them treats for that. Even though they do not know what moral is, they will learn that it is helpful for them from their habits by performing things again and again. Punishing will not be an assistance of parents to make them achieve it.
To sum up with, knowing what is right to do or not is very important for children to be an adult, and the method to teach them is much more important. The key is to provide them positiveness toward the world, because they will hate it when the world is against them and tells them what they do is wrong. In this regard, I think there is no need for strict rules for children to be successful in their life.
