"The property of love is never to seek self, to keep back nothing, but to give everything to the one it loves. Blessed the soul that loves; the Lord has become its captive through love!"
~ St. John of the Cross
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.
