Fools were out and about this week in an investing world jampacked with actions and ideas. Here are three articles you might find useful as you decide how to invest your money.

Follow the Easy Predictions to Profits
Investors are knee-deep in predictions this time of year and might be feeling the strain of sorting out who has the best handle on how to invest in 2011. But take heart; longtime Fool contributor Selena Maranjian reminds investors that they can follow easy predictions to profits.

"[I]f you really want to base your investment decisions on predictions, choose easy predictions that are likely to come true," Selena writes. For example, people take medicine regardless of the economy, and this fact might lead you to take a closer look at drugmakers such as Abbott Labs (NYSE: ABT) and Merck (NYSE: MRK).

Investors in the SPDR Gold Shares (NYSE: GLD) ETF or individual gold stocks might benefit from reading a recent monthly letter written by Howard Marks, chairman of Oaktree Capital. It's "a thoughtful discussion of the arguments for and against gold," Dan tells us.

Or perhaps you have more time on your hands and are willing to dive into Harry Potter and the Methods of Rationality by Eliezer Yudkowsky, an AI researcher and expert in decision sciences and rationality, who uses Harry Potter to teach lessons in rationality.
