As WorldChanging often links to sites and stories which reflect the ideas and activities of younger people, it is worth noting that one of my heroes, a person whose ideas and values parallel those of WorldChanging, just turned 86 years old. Arthur C. Clarke ostensibly writes science fiction, but in reality what he does is show us our own potential. OneWorld South Asia has an interview with Sir Arthur, discussing topics as varied as what he thinks of satellite television and how we can all work to solve issues of poverty and inequality.
In this interview, he utters a line which I think describes our efforts at WorldChanging perfectly: I have great faith in optimism as a philosophy, if only because it offers us the opportunity of self-fulfilling prophecy.
