If we just worry about the big picture, we are powerless. So my secret is to start right away doing whatever little work I can do. I try to give joy to one person in the morning, and remove the suffering of one person in the afternoon. If you and your friends do not despise the small work, a million people will remove a lot of suffering.
I think the most essential thing in one's life is silence. What is silence? We think if we are quiet, we are silent. But we must come to silence without desire and wanting, otherwise we are not silent.
