In My Opinion, it can be important to do volunteer work... it forces one to find real value in work rather than economic value, and it can expose someone to a certain element that one might not otherwise be exposed to. Lastly, it is a good opportunity for those who are unsure about the future to be doing something new with their time and feel productive while figuring out their plans.
That said, I'd like to present two very different volunteer opportunities.
The first is an opportunity that I took advantage of here in New York City. 826NYC is a non-profit with locations in San Francisco, LA, Chicago, and NYC that strives to keep kids succeeding in school, particularly to encourage theirhttp://www.blogger.com/img/gl.link.gif writing skills. It fosters growth as a creative writer, and allows one to forge relationships with children who really appreciate the help and companionship.
The second is an opportunity I've only just discovered. Cross-Cultural Solutions is a way to see the world and positively affect people's lives for as short as a week or as long as almost two months. I may consider it for the future.
