I stumbled across a gem -- the kind I wish I'd known about long ago.
The United Nation's Refugee Agency (UNHCR) has an amazing Flickr account with photos of all the places they have workers on-the-ground, either for long-term projects or for emergencies, such as earthquakes. There's also plenty of pictures of Goodwill Ambassador Angelina Jolie to go around, as you might imagine.
Looking through album after album I felt this great urge to get out there --- wherever I'm needed most at this moment -- and help. These images force you to think about the amount of suffering so many are going through right now. Suddenly, whatever your own personal woes may be -- important as they are -- don't see so top-of-mind any longer.
