I think it should get easier for each generation. I think you should leave something behind for your children as well and be prepared to leave it early just in case something happens to you. Property, life insurance, gold, something.
If my oldest wants something he will save for it, ask what he has to do to get it, or both. He offers to pay for his own stuff already. But he knows he doesn't have to. Up until about 21-23 were providing everything they need. Tuition, rent, etc. By 25 he should be done with school, or his business, whatever he's gonna do and shouldn't need anything from us, but if he does, we got him.
