     Honestly, since my son was born, I have thought a lot about how to raise a child. I once heard a story

that told about when a baby was born. The story said that when a baby was born, a new master was born.

The parents of that baby would become the servants. The question is: Why? Based on my observation, this

phenomenon is true. Most parents who don't pay much attention to their kids have difficulties with their kids'

attitude.

     I'll make a comparison of how two families raise their children. The first one is a family with three children.

Both mother and father never say "No" to their children's demands. As a result, all of their children became

stubborn and won't listen to their parents' words, "We can't."

     The second family educated their children strictly from one year old to high school. The parents never

approved or agreed directly to give their children what they wanted. They always postponed one or two days,

even if they could afford it. Due to the way their parents educated them, these children understood that if they

wanted something, they had to wait or they had to make an effort first. As a result, all the kids from the second

family successfully graduated from university on time.

     In my opinion, if we want to be successful parents and raise our children well, we have to start disciplining

them when they are toddlers but not wait until they become teenagers.
