What's the key to successful investing? That question shows up frequently in my emails, and I always answer the same way: saving. What's the best way to get started in investing? That's probably the second most frequently asked question I see in my emails. I always answer the same way: saving. I never hear from most of these emailers again. I guess they were disappointed in my answer. They wanted a hot stock pick or a foolproof investing system. And I guess they simply don't feel the connection between investing and advice on how to save $10. I can't recall a single email follow-up asking for more detail. Too bad, because my specific saving strategy is exactly the investing strategy these readers were looking for.
