As life becomes harder and more threatening, it also becomes richer, because the fewer expectations we have, the more good things of life become unexpected gifts that we accept with gratitude.
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.
