I think you could certainly suggest they watch a few videos on the subject. They may or may not follow thru but unlike others here I feel it's worth a try. I wish someone had tried to when I was younger. All I remember hearing was why bother were never gonna be able to afford to retire. Well retirement is going to happen for most of us and it's better to start planning for it now.
I especially like this video as it shows how important it is to start early. The more time you have to let things compound the less daunting it seems to reach a goal of a secure retirement.
