If you do not give your children formal education give them home training, religion training and counseling, as they grew up they will quickly understand responsibilities and they will think inline with what they've. Lack of ideas is the most reason for poverty, not money. If you have $3000 without ideas you will beg after 6 months.
Is the idea you are referring to a very general and broad idea that can cover everything? If yes, it means that the idea you are referring to is an idea for managing finances so that there are more of them and you won't be begging after the next six months. Well, apart from that, everyone also needs to get ideas for developing their business before they are too old and regret that they have wasted their time. Because this is needed before someone really falls into poverty due to running out of money in his life as you told about what happened to your own father.
Some cases family traditional background pursues children's destinies unknown to them, so no matter how they struggle nothing to show and before you realizes your age is gone and you end up becoming a parents to other children in poverty...training children early and give them responsibilities it will help them to task an ideas.
The responsibility of parents for their children is indeed very obligatory and also very important because it is to make family life more peaceful and enjoyable. So that educating and training his children is the main thing that must be done by the father in his family before a father regrets the time he did not use before, so apart from having to provide education and ideas for children to navigate life in their adult years, a fathers must also be able to use the time to continue to produce so that he does not live in poverty in his old age.
