over time, our human thoughts will definitely form by themselves (all humans experience that) if we don't guide them then the impact on their future is really big, I can't imagine my kids becoming gambling addicts in the future, it will definitely hurt my heart.
Children have become attached to their parents since they were born, even animals guide their children to be able to live independently. Parents who don't guide their children in a good direction can be said to be failed parents.
I will continue to guide my children even when they are married later, I have given a lot of sweat-money-time-sacrifice for them, if they become criminals or gambling addicts, I am clearly guilty.
That means you are a good parent. That's great. It's only sad that there are still parents who don't care about their children. It can be because their children are too stubborn and it seems impossible for them to be disciplined or it can be the parent are too busy on something like drinking alcohol and gambling but if this was the case then the children are the one who will try to help their parent.
If we are sure that we guide our kids from the start till they became a teenager then that must be enough. Our kids will soon learn how to live on their own. You know, having their own family but they will surely follow the good things that you taught to them.
