It's really startling to me how many successful people are nevertheless quite clueless when it comes to money management. So much so that an entire industry is built around helping people manage their money better, even though most people could do it themselves if they were just willing to learn.

But, going back to our previous discussion (#989851), part of problem is that it's hard to discover high quality sources to learn from. So much of the money management industry is also "self help", but they don't always give good advice, and some self help gurus are outright scammers.
