No greater problem exists, than focusing; for when we focus we lose the big picture, for example, imagine you are a builder – now you have a vision of building say a great oasis that will heal the world etc. etc. but then you decide to build a home – obviously while you are building the house, you have no space in your head for the dream – in other words, focus is the enemy of vision, yet without focus, no vision can actualize! – hence the ultimate ability is to lose oneself within the wisdom of God who will continually allow you to do small big things!
