Makes a huge difference if you can sock away some money in your 20s, as opposed to starting in your 30s.
You are wise. Your family is lucky.
My oldest has no idea how much he is putting away in his company sponsored 401K that he let me handle. I'm not really telling him how much he's putting away, but he's living at home so all he makes is gas in the car and gravy. So when he starts the stupid talk about buying a motorcycle I know at least he will avoid some of the idiotic things I did as a kid.
