2. Experts Don't Know Everything
We put a lot of trust in experts, including stock analysts, economists, fund managers, CEOs, accounting firms, industry regulators, government and a host of other smart people. They all let us down. A great many of them lied to us, intentionally misleading us in the name of greed and personal profit. Even index fund providers let us down, charging us a fee for the "privilege" of losing 38% of our money. If we've learned anything from the experience, it should be that blind trust is a bad idea and that the majority experts can't predict the market.
