I believe there are two types of forecasters: those who don't know and those who don't know they don't know. And you see this in a lot of individuals who are predicting the markets, they're so confident in their calls, their predictions, their stock picks, their asset allocations, they've done a great job of selling themselves on how smart they are. They truly believe they can navigate the markets and pick winners and losers.

That's the biggest mistake that any investor can make is falling for that overconfidence. The best investors I know, the most successful ones, they're always humble. They understand the limits of their knowledge, and they're always learning and adapting.
