Joel Tillinghast on focus

Successful people simplify their lives by focusing on the facts and actions that matter most.  If you don't, you will find yourself either on a hamster wheel or bogged down in trivia.  The trickiest part is staying open to new and contradictory information that affects your goals, while cutting out the clutter.  One test for noise is to ask whether a piece of information will still be useful in a year or two, leaving out plenty of fussy details about quarterly results.
