You must be psychic to know so much about this guy. And you must also be the best parent ever. I bow down to your superior wisdom. I also look forward to your new parenting book to tell me the right way to raise my child. Kudos to you sir.
A few parenting tips.
Spend enough time doing things with your child so he will actually like you are care what you think, feel and say. If the child thinks you don't care enough about him, he won't care enough about you to care what you tell him.
One you spend enough time with him, use that time to encourage positive behavior and give that child as much guidance as that child needs in that area. Some children need more, some need less.
If the child should do something wrong, then when you discourage bad behavior, the child will listen and care what you say. When the child does something wrong, talk about why it was a mistake what they did, and ask what it was they were trying to achieve by doing it. Explain why what they did really doesn't work, and tell them a way that can.
To do this, you need to spend enough time with your child, if you don't, you will fail.
The child must also be convinced of two things for the child to listen to what you say.
#1:They must be convinced you absolutely know what you are talking about, understanding every implication of it, and how it relates to success in life and well being. If the child is not convinced of this, even if the parent seems to mean well, the parent's counsel will be ignored because the child doesn't think that parent knows what they are talking about.
#2 They must be absolutely convinced that you care about their best interests. If they are only convinced that you know things, but don't think you care, they might think you are lying as some sort of game.
You must be smart and caring. One of the two is not enough.
With respect to #1 and #2, you must spend enough time with your child to understand them and their interests to be able to provide them with the information that is most pertinent to them, and thus is the most effective form of guidance. You must understand your children.
If you knew someone who you were absolutely convinced knew everything and genuinely cared about your best interests, you would listen to everything they said, and would do it. Who wouldn't? Simple, but not easy.
By spending enough time with your children having good times with them, they get the association parents=pleasantness, and parents wishes =pleasantness. Therefore, they want more of that pleasantness, so they will care about what you think and will be most likely to obey.
It also helps to be perceived as the most successful person in life they know. It isn't all about money, either. I've met people who have been really rich, and now are not, and it doesn't bother them, so long as they have what they need. If you care about your children and give them good counsel, they will view you as successful in life because you have provided for them what everyone uses money for, which is to achieve the best sense of well being.
Also, a word on dental health:
Dr Weston Price, head researcher for American Dental Association, traveled the world studying various people in the 1940s and discovered that people who ate a natural diet, with no refined sugar,and only whole grains with no white flour or white rice products had perfectly straight teeth, naturally. No braces needed. This is because whole grains provide the nutrients needed to build the jawbone to it's full size, allowing enough room for the teeth to grow in perfectly straight, including the Wisdom Teeth. Sugar dissolves the teeth and bones, and inhibits proper bone growth. Refined grains are deficient in minerals needed to build bones, too. It isn't genetics. Identical twins were raised separately, in different parts of the country, one with white flour and refined sugar products and the other with healthy whole grains devoid of refined sugar. The twin raised eating healthy food had perfectly straight teeth naturally, with a good looking fully formed facial bone structure, but the other had a jaw too small, with badly crooked teeth, was scrawny by comparison.
That's why you don't eat white bread or drink soda. It will make you ugly with crooked teeth. The genetics are just the blueprints. Even with the best blueprints you still need all the building materials the blueprints call for. If they are not provided, the building won't be properly built. Genetics are not magical and thus cannot essentially make a perfect body out of thin air, which is basically what you are asking it to do when you don't eat right and expect to grow up properly.
The only thing that irked me about that was the fact she used a racial remark so easily like that. It's people like that as to why racism is so alive and strong today, no matter what their skin color is. The only issue I had with that lady was she did a piss-poor job of raising her "child", but she obviously felt deeper racial issues towards me.
