-snip- Apart from that, the time we use now is a very valuable asset for ourselves and also for our children in the future, so we should not spend it in places that are less useful for our lives and our children, both now and in the future.
I don't agree that we should spend our money and our whole life for our children in the hope that they can be our investment in the future. Because I think children will have their own lives and we will not always be with our children. But I agree that time is a valuable asset for us to give to our children. Children will see their life from how they get it from their parents. IMO parents should be able to be role models for their children. Parents should teach morals and life values and as much as possible parents should have time with their children to play and learn.
As I said above, sometimes many parents forget that the most important thing for children is not how much money is spent, but how much time we spend with our children in their childhood. Believe me it is better if children imitate our attitudes than they imitate the attitudes of their friends or bad people out there.
