I feel this frequently. I even dream it. Guilt and despair do not generate enthusiastic dedication. We need to show those of good will that they are not as isolated or powerless as they may believe. We ought to call for success stories more often, if only to counter the crap on the television and in the papers.
Someone needs to write out history.
Even more important, discussion on what is being done, what needs to be done and how to do it. Looking at our successes will help us all to see how we might improve the efficacy of our work.
