15 Secrets to Unleashing Your Son's Lifelong Growth Engine: A Competitive Edge That AI Can't Replace

All mothers in the world are difficult, but the path of parenting that mothers of sons must take is particularly arduous.
A son is born as the opposite sex and has a different physical and emotional structure from his mother.
For many reasons, the education of sons is always a subject of inquiry.
"The Secret to Designing Your Son, Ages 0-12, That You Can't Learn for Free" is a book in which a son coaching expert analyzes all developmental stages from birth to elementary school from the perspective of "design" based on 10 years of field experience.
This is a practical parenting strategy book based on the premise that "science is necessary for a son's growth," and the author has personally tested the theory through personal experience.
This book analyzes the golden time for each stage of growth from 0 to 12 years old and presents specific action guidelines for parents to implement.

[You can get ahead even if you start behind]
Remember.
If you don't have children yet, plan to have them as early as possible.
But there's no need to be discouraged in advance if your child's birthday is late.
Even children with late birthdays can grow up to be completely different when they have the wise faith and support of their parents.
Rather, let's use this situation as an opportunity to communicate more deeply with our children, acknowledge their pace, and express true love.
With your wise care, your child will grow up with a stronger mentality as he or she overcomes initial limitations.
A child's late start is never the end.
Depending on your choices, that late start could actually be an opportunity for greater achievement and mental strength.
Yoo Jae-suk, Son Heung-min, Pele, Diego Maradona, LeBron James…
Here's a list of 'late birthday outliers' that immediately come to mind.
I sincerely hope that in the distant future, you will find your son's name on this list.
Here are some must-know practical guidelines for parents of children with late birthdays.

→Practice Checklist: If your child has a late birthday
① Don't compare
I hope you don't do foolish things like getting impatient and expressing disappointment in your child when you see them lagging behind their peers.
Rather, acknowledge that there are differences in the speed of development of children even in the same grade, and explain to your child that these differences are natural.
Parents need to have a clear philosophy on this matter so that their children do not become psychologically shaken.
Comparing your child's achievements with those of his or her peers is the most dangerous behavior that can undermine a child's self-confidence.
② Give them the confidence that 'this is enough for now'
This is an extension of ①.
Expectations should be adjusted to match the child's developmental rate and appropriate feedback should be provided.
Whenever you find yourself thinking, “I’m behind others,” consistently convey positive messages to your child, such as, “This is enough for now,” or “You’re doing well.”
The younger a child is, the more psychological space must be created so that he or she can live with the belief that 'I am doing well.'
Remember that a child's self-efficacy depends entirely on their parents.
Children's perception is quicker than you think.
Adults' impatience and anxiety can be passed on to children, becoming lifelong patterns. Therefore, it's important to maintain a relaxed attitude and empathize with and support children's efforts.

[What's different about children who don't do it?]
Of the children I've coached over the past three years, I can think of three who 'simultaneously' possess both high self-control and deep concentration.
After looking into it later, I found that they all had some connection to smartphones.
(……)
There was a kid who surprised me with his monstrous concentration from the very first class of first grade.
I remember calling my mom right after the first class and praising her for how special she felt.
Despite his young age, he showed behaviors that surpassed the behavior patterns of children his age, such as faithfully following instructions 100% and practicing by increasing the number of steps on his own.
One day, I asked my child this question in the car.
“What game does ○○ play?” The child looked at me quietly and answered like this.
“Coach, I don’t have my phone.” It was a moment where the unusually high level of concentration became understandable.
Just a few months later, the child's concentration began to deteriorate dramatically, almost as if by magic.
It was after my child got a smartphone as a Christmas present.
Unfortunately, I still haven't been able to regain the focus I had in my first year.

[Educational Design: There's a Right Way to Parenting]
The topic covered in this chapter is designing a parenting approach that will most powerfully guide your son's life.
There are still many parents who cannot give a clear answer to the question, "What is the right way to educate?"
Should we raise our children strictly or gently? Should we force them to do things or let them have their own way? Many parents still struggle with these questions.
Rather, as the Internet has developed and more people have been talking nonsense, it seems that it has become more difficult to find the essence.
But in fact, the answer to this question has already been given.
In this chapter, I'll share with you what expert research has consistently shown over the past several decades to be the smartest and least likely to fail parenting approach.
From now on, I would like to suggest an educational strategy that can help you develop your son's unique spirit.

[Hole in the System]
The educational structure addicted to rewards and the educational culture centered on private education are also problems.
Korea's private education system demands immediate results and focuses on short-term achievements rather than long-term brain development.
For example, in the current college entrance exam system, where a child who solves problems quickly is evaluated as an "excellent student," there is no room for leisure or time to wait to develop self-control.
The child becomes accustomed to faster and faster rewards, and waits or patience are seen as 'inefficient'.
This trend is repeated at home as well.
When parents repeatedly hand their children smartphones to choose moments of quiet or do homework for them, the children become convinced that the world will always be there to help them.
Eventually, the brain becomes increasingly conditioned to become a 'circuit that does not know how to wait', and self-regulation is not developed.
At the root of this problem lies the role of parents.
According to a survey on smartphone over-reliance conducted by the Korea Information Society Agency (now the Korea Intelligence Information Society Agency), 70% of Korean parents use smartphones even during mealtimes.
Children grow up watching their parents.
If parents do not control their emotions and show consistent behavior, it is difficult for children to learn to regulate themselves through such modeling.
This is why, even though it is an obvious story, we continue to emphasize the role of parents as a role model.
Furthermore, if parents fail to demonstrate how to appropriately express and regulate their emotions in front of their children, the children will learn to avoid or suppress the signals of emotion themselves.
