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.
Center yourself to God and PRAY night and day "without ceasing." ALL you do, think, or read can be made into prayer. Great music, art, literature, architecture, friendships are, or can be, forms of prayer. What is gained by prayer can never be lost. PRAYER is eternity breathing in time.
