True, if children followed in their parents footsteps the world would be a better place, but it doesn't always depend on the parents.
For example, i didn't feel like managing children, i didn't feel up to it nor did i want to do it and i decided not to have any.
If you decide to have a child you have to work hard
Usually parents try as much as possible to set the beat precedence for their kids at different levels but the problem is always with the fact that they have limited power to control the choices these kids make at certain levels and stage of their lives, getting to certain age comes with some form of independence such that at such points the kids begin to decide for them selves or have some good sense of independence and choices whereby they can choose not to follow with that which the parents has always wanted them to follow because they may feel they now know better but then parents should never stop at any point but always try to make sure they are giving their beat until the kids become full blown adults.
