Hey procrastinators, busy doing nothing for yourself? Then get busy doing something for somebody else. The holidays no doubt have conjured up a desire in you to give something back, so this week’s site offers a place to usefully kill some time. At www.volunteermatch.org, you can type in your zip code and, in a moment’s notice, find a plethora of ways to get engaged. Simply entering “50125” in the zip code query brings up 151 opportunities, from animal shelters to mentoring opportunities. And as you wistfully put off wrapping those presents and prepping for finals, you can do it with much less guilt, knowing you’re procrastinating for the greater good.
