A good lesson for the kids as they have something we all don't.......time. There are many things written around spending less on X, to save long term for Y, but is that enough? Socking a few bucks away a month on a regular basis can give you an excellent start, but don't just leave it there......make it work for you.
I know shaky markets reduce our faith in investing, however there is no denying the fruits of a long term investment strategy. Over a lengthy period of time, these intermittent blips become historical footnotes. You don't want to be one too.
