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.
You can visualize God's light each day and send it to someone who needs help. Your divine nature must reach out and touch the divine nature of another. Within you is the light of the world. It must be shared with the world.
