Saving the World (using little things, small ways)

Over the last couple of months I've been studying Humanitarian and Development Practice at Oxford Brookes Uni with the aim to go off and help people, fighting against injustice around the world. Now that always seemed a slightly huge mammoth task, but I've realised (as I've attended lectures, and read books and had conversations with the amazing people on my course) that the best way to attempt it, is through small, little changes. Changes that might be as small as writing a letter, or encouraging someone to follow their dream, but those changes can escalate till they make a difference on a larger scale. Its the whole cell idea, where one cell will multiply till it could take over the whole body. One of my lecturers as written an entire book on this idea "Small Change" and the way he's used it around the world. Its very inspiring when you feel helpless, as you don't need to have a PHD in saving the world to encourage people to use the inherent skills they possess such as gardening, bargaining, etc to start making a difference.
