Saving vs. Investing - it's basically the same thing, not a one or the other. If you're doing either of these you're doing better than the people that are spending a lot.
Financial security is a dynamic principle. It's relative to what everyone else has. If I have $100 surrounded by people with $10,000, i'm not feeling very secure. If I have $100 surrounded by people with $1, i'm feeling very secure.
Maybe I should be saying - Saving? Investing? Spend, baby spend!
