Dan Kennedy's got a good observation,

as well as some good advice, here:

It has consistently been my experience that people underestimate themselves and overestimate what's necessary for the success they seek. The millionaire entrepreneurs that I know are not much smarter or more knowledgeable than the average person on the street, nor are they gifted or somehow pre-ordained for exceptional achievement. In many cases, they're not as smart as most people - believe me, I've met some pretty dumb rich people. Just about anybody could do what they do, it's just that few will do what they do.
