Imagine the world is made up of many small circles of people. Usually we tend to do things inwardly - We are looking towards the cirlce and do things for ourselves or our immediate friends and family who are in that circle. The text is suggesting that we need to do things differently, to turn outward. This would mean that we start to look at the 'big picture' of all the other 'small circles' in the world and try to help them... this, in the writer's opinion, will make hope real.
