A good friend of mine is moving back into town. She admits she hasn't saved much thus far in life, she's around my age (27) but wants to get better at it and wants to understand everything about it.
I promised to explain as much as I can when she is here because over the phone doesn't work as well. In the meantime I did email her MMM's Start Here article to give her something to mull over and basically my advice is to invest in Vanguard's index funds (after explaining what mutual funds are, and what the difference between active and index is), and I'll talk about IRA and Roth IRA, but anything else I should talk about?
Oh, and I talked about living frugally. She does a pretty fair job as far as I can tell, but I can ask more questions when I can.
