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.

1 Stock for the Rest of Your Life
 Fools know that market timing is folly; they like stocks they can buy and hold for a long run measured in years, if not decades. As Fool contributor Alex Planes explained this week: "Trying to anticipate a price zig will probably get you burned by a zag, and a long-term investor shouldn't be concerned with day-to-day volatility."

Alex presents six stocks that offer solid growth rates, good forward momentum, and good yields. McDonald's (NYSE: MCD), Intel (Nasdaq: INTC), and Costco make the list. Read the article to find out the names of the others and to find out why Alex thinks "international powerhouse" Philip Morris International (NYSE: PM) tops the others when it comes to long-term potential.

Hey, Millionaires! This Is Your Fair Share. Now Pay Up!
 Fool contributor Matt Koppenheffer turned the spotlight on the broader Fool community, highlighting some of what Fools had to say about people needing to pay their "fair share" of taxes.

A few highlights of the highlights.

  • "Aptly named commenter ipaymyfairshare lamented the fact that he is coughing up a hefty tax bill while a friend taking advantage of a laundry list of deductions will pay far less."
  • "DJDynamicNC thinks I'm getting way ahead of myself by bothering to consider what 'fair share' is before figuring out what our society should be providing in the first place."

Read Matt's article to get more of the Foolish scoop, including his observation that a consumption tax -- "far and away the most popular" option -- would hit high-end companies like Coach (NYSE: COH) and Tiffany harder than stores like Dollar General (NYSE: DG) and Kroger (NYSE: KR).

General Motors Braces for a Tough 2012
 Fool contributor John Rosevear reports on pessimism and optimism for General Motors (NYSE: GM). The down news comes from GM CEO Dan Akerson, who "sounded a relatively gloomy note in a recent interview with Automotive News when he predicted that U.S. auto sales would be roughly flat in 2012. That's a dimmer view than some analysts have been taking recently," John reports.

The up news includes Akerson's belief that GM "will retain and maybe even expand on its recent gains in market share without having to resort to heavy incentives spending," John wrote. Read the article to get John's take on the situation, including that "Americans are willing to pay more for a small car that doesn't feel cheap."
