Books and other instructional materials can be enormously helpful, especially in your work.

But I am skeptical of those offering instruction, especially when it comes to financial markets.

Someone in Atlanta who is telling me how to runa certain type of business in Topeka? I get that. There’s no overlap.

But someone who offers to give you a financial secret? Ask yourself two questions:

1. Why would this author dilute their possible earnings from this secret they’re offering me?
2. And next, why are they wasting their time selling me this information for a small sum when they (according to what they’re telling me) could be making a lot more just doing the secret.

Those who can, do. Those who can’t do, teach. It’s not true all the time, but it’s worth remembering.
