Focus
One of the definitions of Focus is selectively concentrating on one aspect of the environment while ignoring other things. (Wiki)
The eagle can spot prey from an area 4.8km away. Their incredible ability to focus on their prey from that distance almost always ensures a great catch. This means ignoring all aspects, ALL other things that could be a distraction and going all out for the pivotal thing that has our focus.
It also means absolutely having the prey(Vision) in our eyesight, not taking our eyes off that vision that will almost always ensure success.
The bible is full of scriptures on Vision and tells us to write the Vision down and make it clear. Put it in front of your eyes like an eagle will keep his prey in his eyesight. Write your vision down, put photographs of what you want to achieve in front of your eyes until such time as you are physically able to put your talons in and see the fruit.
Focus is a vital part of seeing a dream fulfilled!!
